Low Power IR Laser

ND filter? That's ridiculous. Just use any 20-cent polarization film. Then you have variable output by rotating the film in front of the laser.

Your Idea is much better.... It's what I had
in mind.. but using ND filters to reduce power
of a low watt IR Laser is not really ridiculous....

Yea, if low power, the ND filter won't be affected, for high power I'd never consider it.
