Hello.
I would like to know is it posible and whrer I can find info about laser projection on glass.
The problem: I want to project something on a glass with laser or anything else, but I want that most of the energy will not pass the glass, but be rejected back.
If anybody can help me.
Projecting images on glass and want the energy to reflect back? Rather confusing
Are you looking for some kind of optical filter instead? Rejecting light of certain wavelength while permitting certain wavelength to pass. If so, you could try looking at some optical firms like Newport, EdmundOptics, or specifically at Chroma and Semrock.
Do note the laser power and wavelength you are using.
