Re: Caution Eagle Pair
Ok, I added lots more stuff to the OP above.

It seems like the firefly may be for some sort of industrial setting where precision specs are important?
I don't think that I would let go of that one anytime soon!
I have 2 pair of these that I bought a few years ago from
an Asian seller. IIRC it was this one...
http://www.eaglelaser.cn/En/GoodsView/701.htm
There is an OD vs Wavelength chart at the bottom of the Page...
I just did a quick test with those same 190-540 & 800-2000nm
Glasses with a measured 98mW 532nm Laser.
Just looking through the glasses it seemed like only 60% of the
beam power was cut. The Beam profile looked bright green...
I didn't see any yellow/flourescent dot...:thinking:
Then I tested it on our Newport LPM.... the 98mW output dropped
to 0.2 to 0.3mW....
I'm not sure if the OP's glasses are IDENTICAL but they look the
same with the same markings on the left lens..
EDIT
I have another similarly looking pair of goggles but they don't
have the wavelength markings on any lens.
I just did the same test with the same 98mW 532nm Laser and
got similar results except that the Laser melted the plastic lens
on the unmarked pair...
I also noticed different Text Fonts on the Eagle Pair cases...
The left one was the 1st test and the right one was the 2nd
test that melted the plastic lens with less than 100mW.

Which goggles? The ones that block IR or not?
