Did you ever get an answer? I am looking to do the same thing, de-focusing the light of colored laser pointers to illuminate a piece of crystalware from a small distance inside a glass showcase, and achieve a Red, White and Blue effect on it... If you found an answer, can you share it please? Thanks, Michael BuetHello everyone!
I am a newbie here. This is my first time post thread here.
Yes, I need your help! Is Laser a focusing light or defocusing?
