I am just starting looking into this issue and hope to get soem
pointers.
What I am looking for is not small lights as for microscope but rather
what way's is possible in terms of projectors capable of polarized
light .
Second question I wondered ; are ther any way to make a laser produce
a wider beam of polarized light ?
Thank's. |

2 projectors, with each a 90-degree offset polarisation filter in front of
the lens is typical for 3D slide projection, but I guess you already knew
that.

A very slight diverging lens?.... )
It surely doesn't harm the polarisation....

Actually it does. Differences in s and p refelctions at the lens
surface will slightly change the laser polarization.
