Re: Need small (2-mm) flat mirrors

Melles Griot, among others, makes some tiny right angle prisms. You could
either coat the hypotenuse or use them in TIR mode.

By the way, are you sure you want to use a metal coating with a 3W, 1mm
dia., CW laser? I do not have a lot of personal experience with high-power
lasers, but it seems to me you are approaching the damage threshold for the
coating. This may depend on the thermal conductivity of the substrate. At
the very least, that mirror will get hot with a metal coating. I would
consider the TIR prism if feasible. Otherwise, you should be able to get a
more efficient dielectric coating customized for your angle and wavelength.
