I heard somewhere that a thick piece of glass blocks infrared.  I took a picture of my hand behind a piece of glass with an IR camera and it wasn't there! :o

I wonder if this could be used. :-/
 





IF i ever had a high powered ir laser i would definantly get some goggles and even if u tried using the glass how would you like holding a thick sheet of glass a laser in one hand and trying to steady a balloon with the other. :P

But it might block it because black plastic blocks visible light yet infaraed goes through it easy, so maybe the oposite would work to like clear blocks infared.



....lazer..... ;D ;D ;D
 
Why not just spend the few bucks it take to get the proper protective eyewear ?
 
Hey senkat. I don't need IR safety goggls.



I heard about the glass thing somewhere on the internet. I have to find it to see exactly how it works and if it would be effective for use.
 
depends on the type of glass. Common glass likes NIR and will pass it easily but blocks UV. Expensive optical glass blocks IR but passes UV.

Any glass or plexiglass will block far end IR like a co2 laser.

google Fused quartz and fused silica
 
There is no need for me to buy safetly for IR. I don't even have that type of laser.

Its just one of those things you want to see. I'm sure we all thought to ourselves " can I burn this with my laser?".
 
Don't count on glass blocking regular near-IR/IR diodes/DPSS. What you were reading was referring to 10,600nm CO2 lasers. At that long wavelength, glass is opaque.
