Rear side of positioning system

For clarity, I show the rear side of the positioning system here. The optical mount positioned on the y linear motor. The mass of the optical mount is less than 500g and the centre-of-mass is about 20mm away from the motor.

xy and yaw positioning of the sample

This is the concept we consider to position the diamond in the vacuum chamber. Two piezo motors position the sample in x and y (Right-Left and Up-Down). For the angle, actuators on the 1'' optical mounts are used.
