Hi folks,

I have an idea, which may be too big for me...

I am working on a double stacking with two PST40 etalons. While designing the tilt unit for each etalon I was thinking about the following setup:

Usage of a high ratio steppermotor at each etalon. Therefore I can tilt the etalons like I want and I do not need any helix or other construction. Next step would be to use an autofocus routine like this way: 

1. Use the autofocus routine to automatically tilt the first etalon.
2. After achieving the best contrast start the second autofocus routine to adjust/tilt the second etalon.

This looks like a off label use of the autofocus with a 2 step routine.

Would this be possible (I am no programmer in any way) or would this be too weird?
