according to that you can also add,
photons {refraction off reflection off}
to area light source as opposed to,
photons {refraction on reflection on}
in laser.

Havent tried it yet, expecting a less interesting scene
also rgbf .99 glass has no shadow, in contrast to .9 glass
this img shows photons penetrating and reflecting several flat pieces...


recollecting a divergence seems to equal too much light loss.
also tried a wide beam reflected off only flat reflectors, still didnt make it
through second lens.

Only direct light made it thru 2 lenses of .9 glass.
