- ITS AWESOME!!!! That is all!
If you want one, just search ebay for 'dichroic cube'. You can pick them up for a few dollars.
I fear to write anything in the description these days as it just seems to get thing demtzed! :-(

Im not getting anything by selling these... theyre just AWESOME!!!!
just search ebay for ''dichroic cube' :-)
Why am I not seeing an AD on this? Refreshed it 5 times already.
"Dispersion Prism X-CUBE" is a better search term.
eBay is full of scams, avoid and buy from amazon or legit online sellers with real websites. eBay fees are also insane, avoid fleaBay. Everyone gets scammed once or hustled by a liar on ebay, nobody can deny it
derty QWERTY eBay is amazing, I don't know what you're talking about. Don't buy dumb crap from sellers with zero rep
I've bought hundreds of items on eBay and so far I've never gotten scammed even once. I haven't ordered a single item from there where I felt the shipping was unreasonable
Why isn't this video called
"Super Freaky Diochric Sexy Cubes?"
*Solar freaking thorium dichroic crosses that makes water out of the driest desert's air*
AlanKey86 because using the term sexy for something that isnt sexually attractive is pretencious and embaressing
gone sexual

I have a feeling that being stoned in thunderfoots house could be a lot of fun.
Best trip ever
I sort of think he was on this one XD
;)
it's just as much fun getting stoned and watching the videos

I was watching this in awe the way your were showing how the light works going through those cubes, so I called my wife over to show her how pretty the light and all that, thinking she'd be impressed. Well...
At least I think they're cool and want one.
That was advice, not an insult. My apologies 👌

+John Possum Sorry, this isn't a Start Trek reference.
It should be, we could use a little Jeri Ryan action in this channel!
Go back to January where you belong.
Would have been cool if you'd talked about thin-films and why these things work. Some absolutely fascinating science behind it.
30 Seconds into this video and I'm already looking where to get one for myself! Also as a Lighting Designer for theatre, Light Science is something Ive studied for years and Love and Never heard of these things. Thank you SO MUCH for sharing this!
The old style dentist lamps (200W halogen) use a dichroic reflector to reflect mostly visible wavelengths (combo white) while allowing significant amounts of infrared to pass through (so that the patient isn't slow roasted).
Really? Interesting
@@DANGJOS yes
I completely forgot about dichroism. Optics and crystallography really shouldn't blow my mind as much as they do, it's largely geometry at these scales, but they're just endlessly surprising.
TomatoBreadOrgasm the lights are dazzling and attractive, its hard not to be constantly amazed by them
they're basically like hobbits!
Yes, crystallography is fascinating! Did you know aquamarine can help remove negative energy and clear your chakra?
Spoopy meditation xD
Just because one understands and knows it, doesn't make it less beautiful :)
We use a lot of these optics in laser show projectors. Specifically dichroic glass for combining the red, green and blue wavelengths into a single beam, and often times polarizing beam splitters for combining two diodes of the same or similar wavelength before sending it to the dichro array to join the output beam. Even having worked directly with this stuff for years it still amazes me.
I thought I just getting a Thunderf00t's Pink Floyd Playlist intro from that thumbnail.
I like how he has Microsoft Edge, Firefox, Internet Explorer (somehow) and Chrome all pinned to his taskbar.
Dartonal lmao
Standard setup on a new computer. Some people just dont care lol
This is usually done if you do web programming and use all browsers to test it since each browser works differently (especally edge, the fucker)

Miss Firefox.
Boooo... Doze 🤣
I am working for a manufacturer of projectors. We use dicroic mirrors to combine light from 3 LEDs, send this to a DMD chip and then through a lens. It is so fun to watch these things in action.
You should seriously upload more frequently mate. Your vids are awesome, keep up the good work.
YT is not his main job and if he keeps up this pace his videos keep being high quality
My dad worked for NASA as well as the DOD and was part of the optical engineering teams that created the "cold filters" used in many different applications. He gave me many different types of dichroic lenses in all sorts of geometry to play and experiment with. He would give me lenses and different types of lights and I had to write up my findings. I felt like a real scientist and nothing could have made me happier.
These are great for combining lasers, I plan on using one to make an RGB laser. Idk if this was mentioned I didn't watch the vid yet, but it's actually two different dichroic mirrors glued together, one reflects blue, one reflects red, but green passes both, explaining the green effect. And when you rotate it most of the light goes through the glass hence white light. They are also used to combine infrared and red lasers in cd/dvd combo players. Again I didn't watch the vid yet I might be repeating stuff.
I love this video because it's just honest. Thunderf00t found a really cool thing and shared it with us.
Your enthusiasm is so infectious! Thank you for being a timely reminder for me! :)
Thunder foot thank u so much for showing me something that's so awsome but that iv been overlooking for years I now know what I want for Christmas thanks for making the everyday amazing
Always look forward to the nice bit of reason and knowledge thanks Mr thunderfoot.
man you have been touching on subjects that relate to my own research for my 3D printer, and the material science behind it, as well as the recycling/refining unit and some of the energy research to power it all, lol.

Thank You Thunderfoot...often the 'simple' things that mean so much . Cheers
Well thunderfoot you have given me the best holiday gift idea! Kids are gonna have a blast AND be wondering what's going on!! Cool and learninfull!!
Thunderf00t, love your channel. I learn so much about science by watching. Thanks.
I've a few of these, great things to play with. My big one sits on a "tensegrity table" beside my solar radiometer. Fun way to occupy the mind when at a loose end.
Your passion for science is infectious
I used to have one of those cubes when I was a kid. Good fun with light, educational.
Aslo, these are used in 3-CCD colour video cameras.These cameras use three monochrome sensors and by spiltting the light with a dichroic cross cube can use one sensor for each colour.
TIL Thunderf00t is colorblind
I saw no ads.
Might pick some up - Sounds like a low-budget filmmaker's dream come true.
I love these things!
I gave them as stocking stuffers last X-Mass.
Just now saw this video from you and it has inspired my creative side! My mother and brother both have birthdays coming in a few months so I'm going to get a few of these nifty little cubes and put them on a rotating pedestal with an LED light behind it so that it'll slowly rotate through the colors. I think it'll make a nice little (mostly) homemade light that is a lot more interesting than just a basic color changing desk decoration.
4:14 "they're actually used in something you use on a regular basis, they're used in colour projectors"
>tfw you've never used a colour projector before
I would be very interested to see what a laser would do with those
A laser operates at a narrow frequency [one colour] so the result would not be interesting
nightjarflying Does it only have an effect with colour?
There are three filters in the cube. Each one passes a different range of light frequencies [colours] - white doesn't pass through except at peculiar narrow angles of the cube [as when you can see the monitor in Tf00t's video]. See the wiki for "dichroic prism" - there's a good illustration of the principle there
white is all colours you split it up to get red green and blue so if you are useing a red laser you will only have it come out in 1 direction but if you use more then one, a red a green a blue you will have one dot in each direction, and possibly a weak one of each(blue and red) in the green direction
cedmanotro
"nightjarflying Does it only have an effect with colour?"
what he is trying to say is that the colour of a laser is only useing a thin slice of the colour spectrum because they are filtered in the 1st place, if you have a red laser you will not find any other(if it is any good) colour because its only sending out light on the red part of the spectrum of light
there is more to lasers then that but that is what is relevant.
Maybe cedmanotros gut is thinking about the laser as being a modulated (or whatever it is) lightsource. I've never seen a white laser, they might be impossible except as a combination of red green and blue lasers orrrrrr what if what generated the colours had some of mechanism in it that changed the wavelength based on the inputted pwm and you fire at a high hz kind of like a fibre optic fireing sequential colours so fast they become white to the eye. Probs still easier to do with 3 simul. And so would this modulated white light split differently? If you matched the frequency of the splitter to the laser and gave it full bore into it's exit holes would a white laser come out the front or would the cube just produce white light? And would the cube instead be some kind of focus lens as well as combiner for a white laser death ray? Maybe these are the things peaking their interest.
And would it be accurate to say that the two cross pieces can be thought of as mirrors that only reflect one colour? One mirror throws red out one way and lets everything else through, the other mirror throws blue out the other way and lets everything else through and so after going through both mirrows all the red and blue has been stripped out, all that's left is green, which goes where it was going.
If that's how it is, can you swap the trinity out with say subvisible, visible and supervisible? I dunno say 350700? Is that interesting?
love your enthusiasm.
I just ordered 4 of these. dang i bet the seller of these cubes are happy about this video! even if only 1% of people bought some after watching thats a 1000 extra sales that they probably wouldnt have had otherwise.
A mobile hanging in a window made of these would be pretty awesome. Attach little vanes to the bottom of them to catch little air currents to make them spin and twirl around.
For people not afraid to be seen dumpster diving: many projection TV contain a few dichroic optic.
The shape to look for is a large flat screen and the back cover slanted about 60 degrees (0 degrees being horizontal, 90 degrees the vertical line of the front), There is two models:
Model with 3 micro mirror array:
The white light from the arc lamp is separated into 3 colors using many dichroic optic
The image is formed on each mirror array
A cube prism combine the 3 images for projection
Model with 1 micro mirror array:
The white light from the arc lamp goes thru a color rotating wheel
The mirror array produce each image synchronized with the color wheel
The image is projected as is
Brief, there is no cool dichroic optic with the model that use a rotating color wheel.
Beside the optic, I keep the arc lamp, the inverter that drive the lamp and the 400 volt power supply. The lamp is 100 watts, 60 hz operating at about 100 volt when warm. The light intensity is high enough to burn the skin at a distance of 3 feet. You can replace the incandescent bulb in older projector... Create a light beam scanning the sky like in some circus/amusement park or large sports events, ....
The inverted just need the DC power input from 320 volt to 400 volt... no need to be regulated ; just a diode bridge and capaitor would work and it need the turn on command from 3 volt to 12 volt applied on two of the pin on the small connector ; it is 3 opto-isolator... no danger to experiment until you find the correct 2 pin.
What I found neat was that the beams of light coming out of the cube rotated 180 degrees for every 90 degrees that the cube itself was turned.
The genius part has to be in figuring out how to manufacture them.
A single beam splitter is relatively straightforward, but building two perpendicular to each other... That's the kind of thing that would make engineers cry in despair.
I'm getting one of these soon for a projector I'm building, this was super helpful
Thanks Phil. I was struggling to think of something to buy my 85 year old retired physicist dad for Xmas. I think he must be bored with just getting a bottle of wine every year. He will love one of these. The funny thing is, my mum is not exactly scientifically literate, so my dad and I will probably spend much of Xmas day afternoon trying to explain to her how it works. Happy Xmas.
So basically prisms interfering with each other. So simple but fun. Thanks
love your passion while talking bout it..
My cube has arrived. Cant stop looking at it. People at work think im odd. My little girl is going to love it! (She better had anyway)
Adding this to my wish list! Thank you VERY MUCH!
thunderf00t, thanks so much for not spoon feeding me on exactly how they work, I am off now to find out for myself :)) these things are incredible!
Very cool, and what a great use to put them to in the projectors.
Went straight to eBay, top bloke.

I just bought a couple of these for a Christmas present, I'm so excited!! Thank you for making this video
Saruman! He who breaks a thing to find out what it is has left the path of wisdom! (Seriously though I just bought one :)
I have a Red Green and Blue bulb in a 3 light fixture. I noticed that Green does similar things in the shadows around the room. The other colors split the other two colors but the room out of areas of shadow is white. Green acts differently depending which fixture it is in.
You are having too much fun with these thunderfoot
Serious post here.
IMHO, it's time for merchandise. Thunderf00t lab coats, prisms, dichroic cubes, spectroscopes... Lots of stuff for kids to do. I trust your judgement over mine or any general supplier whom I don't know. Ok, I don't *know* you but I reckon that you are as you appear, and that is mostly a fantastic educator.
My 10 year-old grandson has just been made "science ambassador" for his SEN class. If other kids are having trouble, he's to help! We are SO proud, especially given his own... quirks. That'll do. He would love stuff from a web celeb 😁. My biochemist son's in charge of buying science pressies for his niece and nephews, and anyone else who would like one, but he's not allowed to nick chemicals from the lab! Not after... Oops? LOL just kidding. Or am I? 😎
Back to being serious; I've seen a v interesting chemistry channel on YT which shows, amongst other things, how to grow your own crystals - different videos covering different chemicals/techniques. He says that the chemicals can be found on Amazon or other websites - a) that's not very helpful and b) if it were up to me to get the stuff, I wouldn't trust myself to buy the right - safe! - things. Not to mention he has big pots of the stuff. I think an ounce or so would be a more appropriate size for kids' experiments (under supervision, of course) at home. You could write up instructions maybe, or do a video for each? I'm all for immersing my grandchildren in science from a v young age but it's got to be appropriate - no small, especially strong magnets for the 2 year-old for example. You could give reassurance regarding the right age group.
No, I don't want you to stop doing your usual, top-notch videos, but as you yourself said, you wanted to come back to doing science and not cliquey sceptical stuff, and whereas I doubt you'll stop being sceptical (good!), doing it on your own terms and in your own time is by far the better choice IMHO. I'm not sorry (even though I shared your opinions virtually all the way), I get more fun watching you do science, engineering, and taking idiotic "inventions" apart.
But it couldn't take *too* long to get some glowing blue balls to sell, could it? 😉 It could help fund your videos, too. If you want to look into selling t-shirts, hoodies, maybe even lab coats 😇 there is a company which allows you to give a cut-off date for orders, and if you don't reach the desired number for the most cost-effective run, you can stop it before they start printing (obviously, no money from punters until the items are ready). I got an amazing t-shirt through a charity recently which had been mouth-painted by Henry Fraser (I follow him on Twitter. It has a beautiful tiger head on its front and everyone who sees it is jealous! And yes, it's all based on the painting he did only using his mouth to hold the brush!). It is good quality and a reasonable price (about £15 IIRC - or not far off), sold in aid of charity. Maybe they have a more commercial... Was going to say "arm", but I'll leave it there...
Please don't dismiss this out of hand! I'd be prepared to proofread your web pages for it. I've volunteered to proof for charity fundraising, an online shop, mid-Atlantic sci-fi (we wanted it understood by all English speakers!) a couple of dissertations and currently a biochemical thesis and a medical diss next summer. I have 2 BAs from the OU covering a wide range of subjects, inc some science, but mostly linguistics and the technical side of music (I had to proof a handwritten score by Handel for half my own diss! Bloody awful handwriting!). Also have recently joined Distributed Proofreaders to help get out of copyright works online. So I have a few decades of practice at doing it and offer my services free of charge should you choose to go ahead with it. I'm stuck at home more often than not, so I usually have a lot of time. As an aside, I could go over your videos before you upload if you want?
Ann other pear off I's rare lea Hertz, moor off ten 'it yelps ;-)
Sorry for dumping this on you, especially just before Xmas, but I honestly think it would be popular with your loyal followers and could help keep you online and us on our scientific toes! I'm sure that you have other followers who have a ton of experience in setting up businesses online and maybe an accountant to help out - *all volunteers*!
Anyone else agree? If you really don't want to go there, and this post becomes a nuisance, say so. I'll pop back in a couple of days and take it down if you want, or you could do it yourself. No offence taken on my part if you do. If you want me to go over anything, let me know on this video your preferred way of how to contact you.
A perfect gift for my nephew. I'll just tell him that this is the "cosmic cube" from the Avengers movies LOL....
Thank you for showing this I ordered one last night.
Thank you for the Christmas present idea

This is another one that Tim from the Grand Illusions channel would love.
When I was a kid I took things open, and i've found one of these cubes (very small) in a cd player. Thanks for letting me know what this is Thunderf00t!
Dang I love your channel @thunderf00t!
That's quite a treasure there in that Dichroic Cube!
Mind blown!, thank you Mr. fOOt.
Thanks for the christmas suggestions
That is neat as I like interesting things which illustrate scientific principals
The cyan color mid rotation is great
They look like 4 prisms bonded together!
These work on the interference principle, yes? Something like the way multi layered anti-reflection coatings on ophthalmic lenses and photographic lenses. I know the desired results and applications are entirely different. It illustrates as well that we don't really completely understand how light (loosely, because we can go from LF infrared right up to X-ray and beyond) behaves in a wave like manner for some analyses and in a particle (photon) like manner for others.
Double like for showing us this, i had to get some for myself, these things are awesome
This is awesome on so many levels. I might get myself a few of these.
I need this for Christmas! great vid!!
More videos like this! I love scientific curiosities.
Hey Thunderf00t, you've given me a great idea for a potentially amazing disco "ball". I can't wait to start designing it. But I have to work in the morning.
Buying them now, thank you for the tip. Ebay lists some as hot items, China must thank you for the shout out ;)
Thoroughly love your videos. Purchased
They look great, and they're not terribly expensive, so long as you buy them from China. But the delivery estimate stretches to the middle of Jan, so not a lot of good as Xmas pressies :-)
Thanks dawg, these are pretty cool. They'll be good presents for my lil broskies
I started pulling these out of defective video projectors years ago, to show and demonstrate these properties to my friends and generally mind-fuck them into the wonderful geomertry of optical engineering. It's nice to see, I'm not alone. Cheers !!!
The reverse experiment would have been interesting: Take the split beams and reflect them back through a second cube.
They are also used in Disco / theatre lights.
just looked them up on ebay - they have gone up in price! - thank you for sharing
as soon as you said what they were called i hoped over to ebay and bought one :D
such a simple concept but very usefull
They are pretty fun. We have been working a little bit on using a similar optical construction to build a thermal imaging camera in the lab. By splitting the the beams and doing correlation you can actually derive the long wave length parts of a picture with one of these and a standard RGB sensor (if you are interested you can look up Horton, Mitchel Dewayne, "A Novel Technique for CTIS Image-Reconstruction. "). However it is currently a very long computation to do, so it isn't really practical for a real-time video camera yet. Since you have done a lot of great thermal imaging videos I would just let you know the true awesomeness of what is possible with optics these days. You seem like you would appreciate it.
What happens if you try to split one of the colors that have already been split like the red or blue with another cube? Will it make three beams the same color or what?
Davis King the original colour should bend if it wasn’t green but the other colours would be very faint as there is very little other colour light left in the splitter output.
Davis King probably will have one main beam in the colour you’re throwing at it and two very dim beams in the other colours, because I guess $2 pieces of glass don’t split chromatically perfect. But i don’t know, just guessing
...it would probably stay the same as these cubes are basically four prisms glued together. Similar experimet was conducted by Newton who shined beam of white light onto one prism, isolated the beam of single color, and then redirected that beam into another prism. Color remained the same, therefore proving white light is actualy made of all the colors . Here's the video of that experiment: ruclips.net/video/--b1F6jUx44/видео.html ...:)
I assume that the light will stay the same color through the second cube because it has already been filtered into the different wave length, but the only way to know for sure is to experiment and see what happens. I don't have a couple here to try it myself and I don't plan on buying any so it would be really cool in Thunderf00t does it and reports the findings, just to satisfy my curiosity.
welp, never bought something immediately after watching a video before but I pulled up Ebay and found a seller having a sale and got 2 for $6 with free shipping. May not get here by Christmas but for something this cool and cheap it was a no brainer.
Can you do a video on how they work? I have heard of polarization, and used the effect, but one more time couldn´t hurt.
you can also pull little ones out of DVD players, and CD players too I think...I have got a few from old DVD drives when I salvaged the laser and driver module...
You could have gotten a little sponsorship deal for these! The prices on eBay will probably double or triple over the next few days.
No way. I was just playing with one from a rear projection tv. So dope.
Absolutely great video that I might use if I start tutoring film again!
That said I have to nitpick. You called magenta “purple” and you called yellow “green” and cyan “green”
Sorry, had to nerd at you. Love your science videos, please do more!!!
