i really can’t find any relevant info about these questions:
Laser light: it seems impossible to simulate a laser light with blender, since even a spot light source has a wide angle, and object with emitting material won’t reflect properly.
I want to design a laser device, with front surface mirrors, and the sabrelaser demo is no help for me.
Another question is about lenses: can’t find any example of lenses, i’d like to have if possible an accurate model of lens that can tweak the light in a realistic way.
Realistic means for example using a white light source and a prism-shaped “glass” object & material, and get a RAINBOW
Blender is quite good in physics, but i really can’t find any info about optics!!!
If any of you has experience or info about that, this would be very kind to share it!
Thanks a lot
