Hi all, Does anyone know the cheapest way to build a voltage control rotational stage that has 0.1 mrad resolution and can travel +/- 0.02 rad? The load is about 2 lb.
Thanks
John

Cheap? A lazy suzan (i.e. cheap turntable mechanism) with two levers joined by a stepper motor driven screw thread. The radius arms as long as needed for the desired resolution. Or even a long arm on a flexure (a metal tape hinge) Commercial stepper driver.
