Yep, its a class 1C laser nowadays. One of the safety features however, is not that the beam is divergent (its not divergent at the point of treatment), but its intentionally designed, so its focus point are in the plane where skin would be when the device is being used correctly, and then the lens is intentionally made so the laser is unfocused outside of the treatment point. This is one of the mandated safety features for a 1C laser, in addition to a contact sensor. So basically, a wide beam, that is focused to a small area using a strong lens, so the beam quickly becomes unfocused again as soon as it leaves the aperture ("Aperture" here is the end of the plastic tubing, ergo where the skin is, not where the actual laser diode is). The "security code" to enable the laser is actually not a security code (its unchangeable), its more a kind of "Have you read the manual?" check. Have seen this on many things now, not just lasers, but also for example medication bottles for prescription medication. One I got from my doctor had a label on the bottle saying "Opening instructions inside manual" and you had to actually read the manual to get the precise "code" to open the bottle for the first time. It is contact steroids with desinfectant which had some precautions during application (used to treat severe surface infection). Once that, you removed a seal, and the bottle works like any other bottle, so it was only for the first time opening. There are also other things, like dangerous machinery that needs to be "activated" using a QR code from the manual before used for the first time and such. They call it "license activation" or similiar, but actually, the QR is identical for all customers, so its also just a "Have you read the manual?" safety check.
Probably was a Class 1M laser. In medical tech, lasers are allowed to get away with much, MUCH more than otherwise, as long as the whole "if you use it properly" is followed. 1M Lasers are, frankly, absolutely TERRIFYING if misused, just like like this one.
Are you sure about this? The only class 1M I can find is under the newer classification system and refers to lasers that are safe under normal conditions but unsafe when using magnifying optics. I'm not really sure how magnifying optics would modify the safety of this device substantially in that system since it seems to me that the safety device should either render it a true class 1, or considered insufficient protection for "normal use" and therefore make this class IIIB... (Most medical lasers would be class IIIB or IV and the safety is implemented in terms of safe practices, licensing and operator training)
My parents used to have one that was a xenon pumped IR unit with an articulated wand if memory serves me correct. At full power it really packed one hell of a punch. My dad was curious and we decided to do the stupid irresponsible thing we all want to do and aim it at something. Things like ink on a magazine cover would literally be turned into a bright plasma with a loud pop each time it fired, along with a smoldering crater afterwards in the pages. Even with appropriate glasses on I doubt they would be able to fully block it.
@@mysock351C Yeah, at least according to my most recent knowledge (My university years are over 5 years ago at this point) Class 1M is the "We trust you to use this thing properly or die trying" laser. This stuff is no joke and even when properly manufactured, will harm you badly if you decide to abuse it.
@@Squeaky_Ben Your prof was misinformed. The IEC "M" suffix doesn't mean "medical" or have any restrictions on who can use it; it just means the device is incapable of causing harm without passing through an unfiltered collecting optic (e.g., a microscope). For instance, I've used 1M lasers in regional fiber networking links (but shorter connections, such as within a building, usually use regular Class 1 lasers instead). This is also not a medical device. The Warnings section of the manual (googled the product name + "manual" from the first few seconds of the video) says, "This appliance can be used by children aged 8 years and above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning the use of the appliance in a safe way and understand the hazards involved."
@@brainiac75 Just like a quack polarised light unit I got and fixed. Bit useless, might, now it is fixed again, sell it off as well, or try to see if the unit actually does have any actual use other than as a 100W polarised light and heat generator.
Even a Laser for cutting metal can be Class 1. The trick consists of safety measures to prevent any harmful Laser radiation to exit an apparatus. In this case, we have a resistive skin-detector and - hopefully - a 808m, absorbing coating of the acryl tube.
Duty cycling instead of actual dimming is one of those 'accepted workarounds' that bothers me the most. It's so frustrating, especially with LED lighting.
It makes sense in this case though, since hair has to cross a temperature threshold in order to burn. It's also to burn the hair quickly enough that the heat doesn't have a chance to soak into the skin tissue
Thank you, JustPyro! Yeah, there are some interesting ones I would like to examine closer. Unfortunately, they tend to be too expensive for my liking for an unbranded Chinese product :(
Glad you pointed out how the laser beam doesn't reflect in any harmful way. See, class I (and 1C) lasers also include class III lasers that are enclosed in such a way you can't hurt yourself while using the product as intended. It's just like disc readers, they have a class III lasers, but since they are in a case, and inside the device, there is no way you'll be hit with said laser during normal use.
I see a Brainiac75 video and I immediately click it. Always fascinating to watch, and I love learning about more dangerous things, so I can be more confident in my safety when handling them!
Oh, yes. It is always wonderful for me to finally release the video that has taken so much of my time and energy for the last month. Thanks for the early watch and comment, nma794!
1310 and 1550nm we use in telecom is visible at the power levels we use. That was a scary day but I seem to be okay. I often use my cell phone camera to check if light is coming out of a fiber because it's always on me and I might not have my actual power meter.
I love your laser videos, anything laser is cool IMO, and I always find your videos are very detailed and clearly explained. Keep up the great videos and I look forward to more Laser videos in the future! :)
Glad you like them :) Laser videos will always be a part of my channel. My first video ever was about a laser... But magnets videos are also important :) Much more to come on lasers and magnets! And thanks for the early watch!
I was studying lasers & photonics as my initial career in college and I quickly learned that a class 3a/b laser is not merely something that "puts out less than 5mW", and that a class 1 laser was thereby not "less" than that. It truly is astonishing how easily one can bypass safety regulations especially here in america, for awhile simply shipping a 2.1W blue laser without the battery in the same box was considered legal, so people could buy 2+W blue lasers online and have them legally shipped here, with the battery in a separate box... all in a larger box together as one single shipment.
i've been quite a fan of you for a long time. i even watched you as a kid. even if i can't understand, i could at least memorize some facts. have a great day, Brianiac75
I hope you'll create more videos like this about hair laser products. (Maybe a full product review?) I think there is too much miss information/not enough information about this industry.
Glad you like the video! I don't really want to review product groups that I have too little experience with. Though, I might try to buy a more modern IPL epilator and compare the technologies. I am mostly interested in the technology - not whether they actually work for removing hair or not :D
Hello brainiac. At 1:40 of your video you are measuring the light spectrum emittance. What kind of device are you using for this? I am also an laser enthusiast and would love to have a similar setup to yours, thanks!
I collect torches/flashlights/lanterns and many other devices that make light... But I carefully avoid lasers. This is because it is very easy to suffer retina damages from just beam reflections. You can note the same damage occurring to the camera sensor, even if you never pointed the beam toward the camera. Old CCD sensors are extremely sensitive to laser beam reflections from all kinds of objects.
What's the power of a laser inside a laser printer, they are infrared too? I extracted one years ago, and noticed that I could only see the 'dot' (adjusted the focus by using a webcam to view the spot) on a wall in the colour vision portion of vision. Weird how when you look slightly off from the dot, it vanishes (shone on a matte painted wall, at an angle, to avoid a direct reflection). It's also weird that you don't notice that your vision is only black and white outside of the centre part too.
The manufacturer, Dezac, is local to me; that's a Cheltenham postcode (GL53 7ET) on the box, but they also have other manufacture/warehouse/distribution buildings in my hometown (Cinderford), and close by in Longhope. I've only ever known the name as a local 'landmark', "Oh, you know, down by Dezac on the industrial estate."... never knew what they actually did/made there.
Can you do a disassembly on that? I'm curious to what the laser modules inside look like, and the kind of beams they can output on their own, Without the optics in the wand.
I did consider it but this video got long enough as is. I think it can be pried apart for a look inside without destroying it. I must admit my expectations were low for this unit but it is better built and more complex than I thought it would be. Will try to open it if I can without breaking it. And thanks for the early watch, aaron!
Hi friend ! I love watching every of your vidéo, but i’m asking myself everytime if you already made one explaining HOW a laser works in detail, maybe i’m too dumb to find it, or maybe it can be a next vidéo topic ? Love your work ❤️
Will someone please point me in the correct direction. Is Brain using a Spectrometer 200-1200nm? For someone looking to make their own measurements what are you all using.
All I know is, random quality lasers are fun to play with, as long as you do so carefully. Kind of the moral of the story for life in general. Whatever is fun should be played with carefully.
Love your videos. Been watching for a while. I happen to be in the process of getting my face lasered so I don’t have to shave anymore. This thing is a horrible idea for so many reasons haha. Should be done by a trained professional with the proper machine The laser they use though… you would be going full nerd over it haha. The last session was at about 40 joules per pulse. Each shot was two 1ms pulses spaced 2ms apart (I went nerd and studied all the settings they were using). So with some easy math, that’s two forty-thousand-watt blasts per shot. And it goes way way higher. The laser unit weighs several hundred pounds and is on a 100 amp three phase outlet 🤣🤣. I believe it’s 808nm. And yes it hurts like all holy hell from the hair exploding under your skin and every spot they hit is instantly sunburned
I’ve always loved your radioactive stuff videos, I found a new mineral to add to my collection: apatite. It’s a beautiful blue and white mineral which contains thorium. Apparently people put it in their drink bottles to curb hunger. Smh.
always wanted one of these, and modern ones are only like 120 bucks new. just.... I could never figured out if they are safe... why is the one a clinic uses 10 times the size and a single seesion costs 1k already, better filtering?
If you don't know what type of laser you have and don't know what glasses you need you can emulate using a passthrough on a VR headset and it works better to keep your eyes safe better than any laser glasses. Emulated light is safe.
Me lightly confused. If the average energy is lower and the Laser-Powermeter works by how much it heats up during the exposure, wouldn it also show a lower power reading ? I mean if I run my 1kW waterboiler for 1 minute, I would get a higher temp, than running it only at PWM 10 secs on/off for the whole minute. Somebody help ? 🙃
@@Bobo-ox7fj🤔 Hmm sounds fair enough. So basically you mean, the P-Meter reaches the temp, that is associated with 200mW reading, much earlier so the necessary time is within any of the ON-Periods of this laser, as shown in the vid. Am I getting it ? 🙃 THX btw 4 your quick response !
Holy molly! just when I thought this dude couldn't get his hands in something more dangerous he gets this! Never in my life though something so dangerous could exist outside a top secret military installation!
Interesting, I was looking at these hair removal lasers as well. They sell 808nm laser bars at up to 800W for this purpose on the Chinese sites, though they are quite expensive at around $1/watt. Obviously, these are pulsed as they aren't physically large enough to continuously run at full power. I seriously doubt your laser does anything at all for hair removal.
I will consider it. Though I am hesitant since I have to be careful with eye safety and only give correct advice. But I guess I could make a general one about optical density etc. I have an old video with laser safety glasses failing on poorly made green DPSS lasers: You can see infrared?!? Failing safety glasses: ruclips.net/video/r3V5PzTDP7E/видео.html
@@brainiac75there’s a huge misconception regarding laser safety glasses. most people aren’t going to point the laser beam directly into their eyes but they still want protection from reflections, especially when laser engraving. most people incorrectly believe you need correctly rated glasses and that is not always the case.
I have a blood pressure monitor that would beep like that every few seconds while it was measuring... It was so annoying I had to open it up and cut the wire to the speaker.
There is a Hungarian doctor who invented some bullshit treatment with laser (in my oppinion, allegedly) I took one apart and it looks like just a simple pointer diod with 660nm. It's called SafeLaser. You might throw a test to that to.
this industry should realize that it is not the power of the laser is dangerous but the power density. I tore down three cheap laser pointer from china, removing the lenses makes these lasers as very efficient light sources-using so little power for the output.
I'm not an expert either, just a nerd with a disproportionate interest in the safety side of things, but my understanding of laser classes is that class 1 is pretty much reserved for devices where the beam is completely enclosed (eg Blu-ray burners are class 1 even though the diodes in them are capable of IIIb to IV level power output). Not convinced that this would qualify given how easy it is to even just accidentally bypass the safety features though
Har du set, hvor lidt hår jeg har på synlige dele af kroppen :D Må også indrømme, at jeg har arbejdet så meget med kraftige lasere og sikkerhed omkring dem, at jeg instiktivt har svært ved at fyre en fokuseret klasse 3B laser mod kroppen... eller også er jeg bare en kylling ;) Tak for at kigge med, klatzig!

Failing safety glasses: ruclips.net/video/r3V5PzTDP7E/видео.html
@@brainiac75there’s a huge misconception regarding laser safety glasses. most people aren’t going to point the laser beam directly into their eyes but they still want protection from reflections, especially when laser engraving. most people incorrectly believe you need correctly rated glasses and that is not always the case.
Those beeps drive me insane
I have a blood pressure monitor that would beep like that every few seconds while it was measuring... It was so annoying I had to open it up and cut the wire to the speaker.
What hairs are planning on removing?
They're usually for "unwanted hairs"
Arm pits, genitals... whatever the customer wants...
Sounds crazy to me! No way man...
There is a Hungarian doctor who invented some bullshit treatment with laser (in my oppinion, allegedly) I took one apart and it looks like just a simple pointer diod with 660nm. It's called SafeLaser. You might throw a test to that to.
The epic music though...
this industry should realize that it is not the power of the laser is dangerous but the power density. I tore down three cheap laser pointer from china, removing the lenses makes these lasers as very efficient light sources-using so little power for the output.
Laser Diode 🤔
Well thanks to the skin sensors the laser could go very directly into eyes, but that's just me thinking outside the box.
100 Danish Kronen is just 13 euros! Where i can get these kinds of deals!?
With that laser I can make amplifier because it has irfz44n
Jalapeño peanuts sounds delicious.
I'm not an expert either, just a nerd with a disproportionate interest in the safety side of things, but my understanding of laser classes is that class 1 is pretty much reserved for devices where the beam is completely enclosed (eg Blu-ray burners are class 1 even though the diodes in them are capable of IIIb to IV level power output). Not convinced that this would qualify given how easy it is to even just accidentally bypass the safety features though
So did it work to remove hair?
I bet you tried it, right?
Maybe some fried ball or abdomen hairs? That is what I would have tried.
Cool
Thanks for the very early watch and comment, texastank :D
The lady on the box is pointing that thing awfully close to her eyes!
Really cool
Jeg synes faktisk at det er for dårligt at du ikke demonstrerede hårfjerningen 😄
Har du set, hvor lidt hår jeg har på synlige dele af kroppen :D Må også indrømme, at jeg har arbejdet så meget med kraftige lasere og sikkerhed omkring dem, at jeg instiktivt har svært ved at fyre en fokuseret klasse 3B laser mod kroppen... eller også er jeg bare en kylling ;) Tak for at kigge med, klatzig!
I love lasers and I'm very consciously staying away from them, because I love my eyes much much more.
hi brainiac
Hi! Thanks for the early watch and comment.
If i closed my eyes, could this be used for face hair removal? How long would it last?
Now, idk about any other cishet men, but I like my women to not have their eyes shot out with lasers!
Even a DVD is class 3
Can it cause cancer?
No, at this wavelength each light photon simply does not have enough energy to ionize or chemically change DNA. No worries there. Thanks for watching!
Only if your skin is quite dark and through prolonged use, but you would burn yourself quite alot before that.
Never knew you were Danish.
May be class 1 due to all the safety’s it has
Almost Hidden💀🗿
Yeah, it is surprisingly small ;)
Sooo, don't jam it into your eyeball and let it rip: Gotcha!
I bet the DVD intructions sucked anyways
Nice
The Philips version burnt a hole is my girlfriends leg on her tattoo 😂 smelt atrocious.
Nice video seems dangerous
Lol.
That's a lot of beeping
So I guess it's still safer to use IPL for at home hair removal?
What is IPL?
ET phone home 😂
Also who knew something on the spectrum could be racist
You got the E.T. reference right ;) Thanks for watching!
@brainiac75 love your videos, especially when they involve radiation and radiacode
And I haven't seen ET in years (probably still have it on VHS somewhere)
@@brainiac75 Who out here does NOT know that little tidbit?
I kinda anticipated that little joke as soon as I saw the night-mode shot, and chuckled. An instant later, you actually said it! 👆
Its most likely 1M or 1C laser
It's called 'Pulse Width Modulation' my friend... and is the staple power management of most modern devices
Not PWM, but duty cycle in this case, it's not modulating any width, just time spent on/off
hi
Hi, Mohammad. Thanks for the early watch and comment :)
