These tend to be expensive but in perspective become less of a price factor as you climb the projector spec ladder (in perspective to the rest).
I was wondering: Has anyone build a motorized dichroic mirror mount or are there manufacturers selling these mounts seperately (and potentially not at astronomical cost) ?
My first guesses are no due to how scarce the demand/market could be for this potentially.
Back in the day, we just used 2 part epoxy and glued the dichroic mirror onto the motor shaft of a small 12 volt DC motor. We did this as a quick and small foot-print solution for color modulation of the main output beam of a 1-2 watt krypton ion laser. The dichro dimensions were approximately 10mm x 20mm. Sometimes we used two 10mm x 10mm dichros, each with different color properties. The two 10 x 10's were epoxied together to make one 10 x 20. The long axis of the 10 x 20 was glued perpendicular to the motor shaft.
But then, the best way to "build a motorized dichroic mirror mount" all depends on what you want to achieve with it.
