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.

Thanks man. I never knew infrared could leak out. Love your vids too very informative.

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

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. Just pick those “Eagle Pair® 190-540nm & 800-2000nm Laser Safety Goggles” even the $50 “190-540nm & 900-1700nm” pair would suffice.

how are you measuring or rating the laser 301 for instance?

would have liked to see if those protective goggles would filter out all the visible light had you passed the beam through it alone

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?

So going out side in sunlight your eyes are exposed to a pretty high amount of IR I can't imagine a low powered green laser with some leakage causing issues unless you stare into the laser or a reflect into your eyes for a period of time. I mean if it was say over 100mw yeah get some protection but at the lower level doesn't seem like that big of a deal. I work with a lot of IR related stuff with satellites and I can say for a fact your more likely to damage your eyes being out in direct sunlight.

There's some very good info here to consider. Many thanks!

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.

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? That is, when the beam will always be pointed directly away from any person's eyes? Very interested in the risk assessment for that type of use of these devices. Many thanks indeed for your excellent video presentation :-)

hey, do you know where i can get an ir filter for a laser 303 and also can you put a filter in yourself

how do you know how strong the IR is? what does that detector require, to glow the red dot?

@mohamedalitalaat7730

3 жыл бұрын

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 303 laser also does that

If installing a IR blocking filter will a 808nm filter be good enough or is there a significant amount of 1064nm as well?

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?

@mohamedalitalaat7730

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.

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).
