@@vincenttremblay2580 It wont blind you instantly because a laser like that is much higher than 5mw to just instantly blind as soon as you look at the beam but if the light is focused right on your retina then you will have problems
@@vincenttremblay2580 I'm far from an expert here, but one thing that nobody (at least in this thread) is talking about is how MUCH of the laser's total output power is reaching the destination in the form of IR light. The vast majority of the IR light generated by the laser is converted into green light and only a small fraction passes through, surely. To determine exactly how dangerous it is, we would need to know what the power of the residual IR light is for each of these pointers, and compare that to intensity levels known to be dangerous over a given period of time.
Survival Lasers (The company from the link you listed in the video description) has a pair of goggles that protect your eyes from these dpss lasers. They are only 60 bucks too, which is only $10-20 more than a pair that wouldn’t block unfiltered IR light.

IR wavelength laser emissions, pointed from any distance into an eye, are going to be very likely most hazardous. When using these green laser devices emitting around 530 nm, of the power and technology you're discussing, and pointing the beam either into the night sky for amateur astronomy purposes, or bouncing its brilliance off a painted white interior wall surface, from say 5 to 20 feet away, under such conditions how would you judge safety?

@@joshs2444 a retired doctor not a laser expert but infrared is heat its not going to burn your eye from looking at a beam , its just gonna burn your retina with a dorect hit or direct reflection , or up close reflections id say, just going off first principles
Excellent video!! I've never seen a green bluish laser before. Very useful information, the next time I'm gonna buy a laser with IR light filter lol! But, could you tell me how the IR light affects to the human eye?
Prolonged exposure to IR radiation causes a gradual but irreversible opacity of the lens. Other forms of damage to the eye from IR exposure include scotoma, which is a loss of vision due to the damage to the retina. Even low-level IR absorption can cause symptoms such as redness of the eye, swelling, or hemorrhaging
I bought my son a laser 301 from Amazon and one day later I'm already having issues with it producing a consistent beam. The brightness fluctuates and it's clearly not outputting a consistent amount of power or whatever. Are problems like this typical of these lasers? Is there a somewhat reasonably priced alternative, even if I have to spend more? Do the direct diode ones mentioned in the video have these problems as well? Thanks in advance.
Maybe I'm missing the obvious answer here, but didn't you kind of skip over the whole title of the video? It's not immediately obvious to me that seeing small amounts of IR in laser form is dangerous at all. In fact, I work around a lot of machinery that uses spinning IR laser turrets in highly controlled manufacturing areas and I have never heard eye safety once be mentioned.
It can take a LONG time for regulations to catch up to technology...even decades. Sometimes just ignorance, sometimes political forces at work. Also, short-range scanners like those SHOULDN'T require much power at all, and the amount of time actually on a given spot on the retina would be minute. Such SHOULD be safe for even prolonged exposure at less than 2 feet...BUT for various reasons may be unsafe (including aging of things like capacitors used in the power regulation circuitry, or damage/misalignment over time of any optical filters on the scanning assembly).
I have this in red, started to glow weak so i tryed both recharhing the battery that came with and change it out with a brand New one.still No luck for a good strong beam agian. Anyone knows whatsup with it?
I bought one off of amazon and I bought some laser goggles but I don't think it blocks all the light do you think I should suck it up and buy some expensive green and UV laser goggles ?
At about 05:57 - 06:01 you state the 532nm LASER pointer you are showing is "rated at 35mW", yet the label clearly rates it at < 1mW (a Class 2 == Class II LASER). I see similar disparities at other points in the video, but the image at this timestamp is very clear. Have you done something to boost the output power of these pointers, or are you stipulating a measured value (which indicates either very miscalibrated equipment or incredibly erroneous labeling)?
It's been 2 years, but still let me correct you... These cheap 301/303 lasers are manufactured by Chinese companies, and are way beyond their shown limit of 1mW or 5mW, they can be of 50mW or beyond, they can burn matches... I don't know why companies do this false branding, but it's dangerous, for people who don't know much about lasers
@@TheStarDreamer I'd say Chinese companies do this because they want more sales and aren't bothered by the ethics of mislabelling the lasers. They can market them as being much more powerful, but if the label says they are 'safe' then it's less likely to be banned or withdrawn from sale. Essentially they get to present the lasers to buyers as being powerful while presenting the lasers to regulators as weak and safe.
what mw would you recommend to dazzle a potential attacker day and night please, I was thinking of getting a green between 5 and 50 mw and using an attachment to disperse the light and dazzle.
You need a laser power meter to measure the IR laser after you block the visable light, you can measure the power of the IR laser. You may need a camera or glow card to view the dot. Some cheap detectors requires that you regularly expose the glow card to the light.
so basically if it isn't pointed or reflected into my eyes then i'm good right? looking @ the beam being projected (while behind the laser) isn't going to damage my eyes right?
Yes, for class 3B lasers or less than 500 mW, if the beam is fixed and shined to the wall, you should be safe. However, if you shined the laser to any glass e.g. a window, the IR laser may be reflected to your eye so, you need to be very careful on which surface you are lasing.

XM360, in this video ruclips.net/video/UV9uo-RAazk/видео.html at the 9:30 mark. Where you wearing laser safety goggles when pointing the laser outside in the daytime? Or how about when you uses it outside at night? Where you wearing laser safety goggles then too? If so, then what kind where you wearing? Are there laser safety glasses that can block infrared light and that 470 nm blue light?
So I brought one from temu a 303 green 532 lazor and had no idea it admit radiation already done flashed it on me and ppl (not the eyes of course) but now I'm nervous about that
Doesn't this problem persist with red DPSS lasers as well? All of the models you showed come in red variants as well and they probably pump IR just like the green ones, only having a different gain medium to produce light at red wavelengths.
Can looking at the beams and where they hit on these types of lasers shown be bad for your eyes unprotected? I'm not talking about a direct eye hit into the laser, just using the laser at other objects? I got one of these green ones off Amazon for 40 dollars and it's BRIGHT just looking at it hit the wall for example.

well its not a big deal for small powered lasers, but for higher it is when using the laser you cant tell when that IR is bouncing off some wall or reflective material, thus having a higher chance of prolonged focused light in ur eye that can lead to eye damage
here’s something i just discovered last night and think it’s pretty interesting. i’m not a nerd so i don’t understand a lot of this stuff, but anyway i got a green laser from ebay it’s supposed to pop balloons and light matches but it doesn’t. it does produce a small amount of heat after several seconds. now the interesting part, if you shine it on any part of your body where you have a tattoo it burns you pretty quickly, why is this??? i also done an experiment on a balloon using different inks and markers but the only one it responded to was the tattoo ink. can you explain??w
@@gregoryratliff73 it must be a more absorbent color and material. They absorb more energy and so get hotter. Try doing the opposite with a reflective mirror like material and it won't get hot.
I would presume it is because a tattoo is quite literally microscopic pieces of metal suspended in ink that gets injected into a layer of your skin. So your tattoo is metal and ink trapped under your skin and metal is very conductive.
I got one recently.It's cool to have but i agree it can be dangerous.Keep out of reach of children.Don't shine in mirrors,windows and other glassy objects that can pontentially reflect back into your or somebody's eyes.I don't shine it South outside my house cause we got multiple close neighbours.North of us is an open field which is perfect for using it as long it's clear of farmers.

well its not a big deal for small powered lasers, but for higher it is when using the laser you cant tell when that IR is bouncing off some wall or reflective material, thus having a higher chance of prolonged focused light in ur eye that can lead to eye damage
After seeing his name I remembered xbox 360
Are there green lasers under 5mw?
9:28 Don't cross the streams.
What about purple 405nm?
here’s something i just discovered last night and think it’s pretty interesting. i’m not a nerd so i don’t understand a lot of this stuff, but anyway i got a green laser from ebay it’s supposed to pop balloons and light matches but it doesn’t. it does produce a small amount of heat after several seconds. now the interesting part, if you shine it on any part of your body where you have a tattoo it burns you pretty quickly, why is this??? i also done an experiment on a balloon using different inks and markers but the only one it responded to was the tattoo ink. can you explain??w
Dark colours absorb light. Your tattoo is darker than your skin i presume and that's why it burns. Matte Black is probably the best to absorb.
It’s all about the black colour of the tattoo
@@ponnannakb i never said it was black ink
@@gregoryratliff73 it must be a more absorbent color and material. They absorb more energy and so get hotter. Try doing the opposite with a reflective mirror like material and it won't get hot.
I would presume it is because a tattoo is quite literally microscopic pieces of metal suspended in ink that gets injected into a layer of your skin. So your tattoo is metal and ink trapped under your skin and metal is very conductive.
does it hurt to go thru a window to scare birds??
Don't do that, u could blind them even 5 mw
Just dont point it at your damb eyes and you will be ok. I promise no one puts on laser safety glasses and points lasers straight into their eyes 🤨
You can accidentally hit a shiny surface and the beam may return to hit the glassses
Dude you’re the best you tuber ever I watch you at least 2 times a day
