The IR filter in a visible wavelength DPSS laser (yellow, green, or blue) is a small, thin square piece of blue-green glass.yellow said:do, I remember also seeing a link, but was also not able to find it. Hopefully one still knows.
As this title my find some guys who can answer:
Is there an easy way to check any laser if there is an IR-protection built in, say something like: "if You see that black colored window, then its an IR-filter?"
unfortunately black glass is a daylight stopper, so IR will look different. (?)
Actually, it's fairly self-explanatory.firefly said:What's the difference between absorptive and reflective?
Ashton said:I was told on another site by a reputable party that IR filters could also be almsot transparent amber-colored glass..? is this correct? (I've got one I'm wanting to use in a DX 100mw greenie, or possibly that otehr 200mw greenie if it turns out to really be ~200mw for ~$200)
