The room was not dark. The low readings on the 25mW laser could be affected by that. I'll have to do some more testing. Is it really possible that the 200mW laser is putting out 50mW of green and 105mW of IR? It seemed like a lot to me but theoretically it's possible I guess. As for the...

Just thought I'd share some testing I did tonight with a few pairs of safety glasses and two different green lasers. I'm testing using a ThorLabs benchtop power meter with photodiode sensor. I have a green laser pointer that I got years ago. Fairly bright but never tested before. I also have...

Well, the LaserCheck has a dead battery and they're not user replaceable so that's probably out. Might see if I can crack it and replace the battery myself. Otherwise it's non-serviceable. The ThorLabs has a couple sensors with it. One is photodiode 400-1100nm but 50mW max. The other is...

What do you know. It turns out that I have access to a Coherent LaserCheck and a ThorLabs LPM so I guess I'll play around with those and see what results I get. Much better!

Agreed. Remote controls should be around 870nm or 930–950nm so it's possible. The NIST study was pretty confident of consumer cameras being able to detect IR emissions from unfiltered green lasers at 808nm and 1064nm but it's still a quick and dirty test. I have an old Russian night vision...

No, sorry. The glasses came with a 450nm laser but I was using them to test a 532nm laser I've had for years.

Yeah, I'm not confident in the HDE glasses at all. Got a pair with a cheap 450nm laser I bought off eBay to play with. Getting better glasses delivered today. As for the test, yes the dot visible through the HDE glasses is likely fluorescence (which is not surprising). However, it's just as...

I've read the NIST paper but it occurred to me to try a different test. I'd like to hear feedback on the validity of this. My cellphone front camera is very sensitive to IR. A remote control looks like a flashlight. So, I took my green laser and put it against HDE red 405-532nm glasses...

Actually, I believe I was wrong. Finally took a look at night. I think it's 445-450nm.

Yeah, that was surprising. I'm not sure how they're getting away with it. Other listings for lasers (like the Thor II) say 5mW but have pictures showing over a watt on a laser power meter.

Ha! Yeah. I didn't even look at the specs. The color seems right for 405nm but who really knows. The only reason I got it is because a friend just got one and it seemed decent (and tested at 1W on another friends LPM) and I had some eBay bucks to spend. Looking forward to checking it out...

It's one of these... New Aluminum 1W 405nm Blue Laser Pointer Pen Power Beam Burn Cigarette + Glasses A friend has one and it's putting out 1W. I read some other tests here and they were in the 800mW to 1W range. Not something I want in my (or anyone else's) eyes for sure.

Sorry, I did an edit! I thought you were talking about a review on the Uvex SCT-Orange but you meant the HDE's. I only need one frequency but multiple pairs so my friends and family don't get blinded either!

Yeah, the reviews for the HDE's is what put me off them (and why I ordered the UVEX glasses to try).

The one's I have are embossed with ANSI Z87.1 on the lens and on one arm. No OD markings. Looking at the pictures they seem identical but... After doing some reading I went ahead and ordered a pair Uvex SCT-Orange glasses to try. From the tests people have done, I feel safer with those than...
