Re: Laser Barrels V2. GB. Second run.
If my tax return beats your end date then I will pick up a couple. Thanks for the honesty on the eta too. I would rather know there is no good estimate than make plans based on a faulty one.
Re: Laser Barrels V2. GB. Second run.
I hope it isn't too soon to ask, but do you have a rough estimate as to how long these will take to arrive? Say, from the the last order date of 4/20?
I have a pair of his safety goggles for red lasers and have no complaints as of yet. Granted I've only had them about a week. They do what they are supposed to do, and block more than I had hoped they would. What was the problem with yours?

Please add me to the list if anyone backs out.
I forgot my camera, but I'll try and take a couple pictures when I get home.
For what it's worth, I was playing around with them a bit and they appear to block less light than my sunglasses. I took a surefire flashlight (a friend of mine measured the spectrum this particular LED emits and it...
I haven't tested the e-bay glasses with a photo diode yet, but just from viewing the beam through them I'm fairly impressed. They came in a decent case with a cleaning cloth included. If I shine my laser at a white wall I can barely see the beam. I was less than a foot away from the match head...
I've had the bags from DX cut open by the department of homeland security, with a big green strip of tape to reseal it. Nothing was missing, just gives you a funny feeling when somebody goes through your stuff like that.
Watts=Joules/second. The pulses from that laser are probably about a microsecond long (just guessing, but it seems resonable). Which gives about 200,000W. Give or take a factor of 100 based on pulse duration.
Compare the pictures from the zonestealth page to the group buy red goggles, granted the pictures aren't great, but they really do look like the same thing.
I just compared the pictures from the safety glasses group buy to the glasses I bought off ebay and they look remarkable similar. We'll have to compare once I get them and see if they are in fact the same thing.
Well I just finished testing the transmittance for the Uvex glasses. I was rather disappointed but not really surprised. Approximately 55% of light was transmitted. I don't have any mW values as I was using a photodiode and just comparing the relative output voltages minus the background. I...
I ran across this on ebay.

Should be getting some numbers for transmittance tomorrow. There is an obvious visible dimming of the beam when the glasses are placed in front of it, but I would like to know how well they actually work. I don't think they block quite enough for my comfort so I ordered a different pair that I...
