I've rendered a better version for my lab report. Just thought it
*might* slightly interest someone out there.

I just want to point out that in my experiment, twisting the half-circle
lens 30 degrees would cause the light beam to bend 20 degrees. So I
tried it in the scene and it worked. The dark sphere is 0 degrees, and
every other sphere is 10 degrees more off.

This is really interesting.  Next year when I take AP physics I'll be
able put POV to practical use, Homework :-)

Cool.

But make the beam red, so that it will look like a laser (thus, not
raising the question about color splitting).

Best,

looking good. Hmm, colour spectrum seems perfect :-)

The light beam doesn t only "bend" of 20 degrees
but is also slightly reflected at 120 degrees ;)

It's NOT a laser. The  cylinder on the left is a flash light, with a
piece of plastic blocking it. There is a thin, long, hole in the plastic
which allows a thin beam of *regular* light to go out.

But such a beam would break up into different colours after leaving the
prism. The standard POV can't simulate that. By using a monochromatic
light source such as a laser this wouldn't happen (and the output of POV
would be correct! :-) ).

I handed in the lab report today, but I would like to know how to
specify a spectrum for the light source (in UVPOV)
