I've browsed a few laser safety glasses sites and have come up with a few more questions than answers. So what better place to come than CPF!
Question number one.
Should I worry about filtering the ir frequencies (808 and 1064 I believe) if I am not going to do any pointer surgury or modification or just get the straight 532 nm and save some money. Mostly I would be pointing in the sky with no glasses needed (astronomy outings) but every once in a while I like to take it out and see the beam in the privacy of my home and marvel at it and check the batteries (my excuse).
I notice the glasses that have all three coatings are not as clear and more expensive so if there is no chance of ir leakage I wouldn't think I would need the extra two coatings..right?
Question number two.
The coatings seem to vary in intensity and have number values as to how much of that wavelength they block. This makes sense because lets face it if they all blocked out 100% of the wavelength you wouldn't see a darn thing. So whats a good tradeoff between seeing your beam in the air and being protected from a reflection. How many layers or what value of occlusion?
Question number three.
Any specific recommendations on a comfortable affordable set of laser safety glasses that incorporate the answers to questions one and two?
Thanks in advance.
