IR Laser Safety Glasses

[mikeoxlong]

Don’t know since work paid for them.

Old thread but I had to bring in my glasses from my work truck for an audit and thought I'd share what I use.

Mine are Glendale LOTG-DIODE TEL. Looks like they cover 804nm-1755nm which covers all the wavelengths I would encounter during a typical working day.

What OD rating does it have throughout that range ?

Alibaba, Ali Express, and Banggood.com all sell protective eyewear for various wavelengths of lasers.
Also Alibaba and AliExpress both sell powerful blue and green lasers if you want to have some fun. Just use care and always wear your eye protection!

I'm not sure I'd trust any of what those companies sell.

If you want to play Russian roulette with your eyes, please don’t. We’ll end up having to pay your disability.

Looks like:

Wavelength​	OD​
804 - 1755	3 - 3.1
1064	5 - 5.1
1065 - 1440	4 - 4.1

Also found this:

Tks & IMO 3.0 is mediocre protection for 905nm exposure in this little hobby of ours. If you're a 'Tester' (a/k/a Shooter) of Lidar defense systems, your glasses are unacceptable.

As an active Shooter of/for Forum members I use OD 5 only for best protection in my semi-frequent usage !

You know, in thinking about leveraging a lidar gun in its intended use case, I’m not sure I’ve ever seen traffic enforcement wearing special eye protection when using them and clearly drivers aren’t expected to do so.

I realize in typical use cases drivers are hit only briefly, which helps reduce risk, while during our testing we might endure prolonged exposure. But as the person operating the lidar gun, it seems the parameters of use aren’t markedly different, right? Whether you’re shooting one car repeatedly or 100 different cars, isn’t the outcome for the shooter essentially the same?

The danger isn't from the lidar beam that comes back from the gun, it's from the jammers shooting hundreds of pulses back to the gun/shooter.

That makes so much more sense. Thank you for reminding me.

@Deacon
Even more important to remember is if you're using a Lidar gun that has magnification lenses (eg: TSS or LaserAtlanta) your IR exposure would have much more focused intensity to your pupil.

I have to find where I ordered, but with shipping they were less than $20.


EDIT: I ordered from www.rajsupply.com

Found the specs for these $10 pair. Seems to be what we need.
Lens Technology


5.0 IR Filter Lens: Commonly used around welding sites or for medium to heavy cutting and medium to heavy gas welding.

Visible Light Transmitted 380-780nm	2%
UVA, UVB Blocked 200-380nm	99%
Blue Light Blocked 400-700nm	99%
IR Blocked 780-2000nm	99%

 

[VariableWave]

I had picked up a few IR Glasses...

I use these when shooting... but when using the PL3, the HUD goes blank viewing through when wearing.

3.0 IR Filter Len

IR Blocked 780-2000nm

95%

and these for anyone standing next to me

+1.5	1.5 IR Filter	S2514R15
+2.0	1.5 IR Filter	S2514R20

IR Blocked 780-2000nm

83%

When targeting LJs, especially my setup I did at one testing site, if you didn't have something one, you felt the effects.

Eyesight is important.
While all the jammers are technically eyesafe (minus LE10) a few of us have experienced some unpleasant symptoms after a long meet. Myself, mrkookm, and snoopy have all purchased these glasses and are happy with the quality. (correct me if I'm wrong guys)

So how sufficient 1 - 10 are these glasses for our testing needs vs a more expensive pair is the general consensus

 

[beachump]

Not sure how scientific this testing was but......
I use a night vision scope to see the beam pattern on a wall. When shooting thru the Pyramex V2G goggles, the beam was dimmed significantly.
When trying to view the beam on a $140 ThorLabs IR viewing card I could barely detect it. Thru the goggles, nothing.

What did you compare them to?

 

[NoahWL]

Did some research and took a chance on LightObject's goggles marketed for fiber lasers. I can't seem to find the others I was comparing them to, but the unique color of the lenses led me to believe they may be similar to some of the higher end goggles. Unfortunately I have no scientific way to test them to know for sure, but they seem promising: with one of the goggle's lenses covering the transmit lens on my PL3, an ALP does not alert to point blank shots aimed directly at an RX head (at least not outside in the shade, during daytime). I don't know what that means as far as providing protection from higher powered lasers, though.

[beachump]

What did you compare them to?

Only with and without those specific goggles.

Found them on amazon prime as well in case someone doesn't want to use a sketchy website tho probably legit merchant, only $5 more really https://www.amazon.com/dp/B003UUB85S/?tag=rdf0cd0c-20
