Question ID: 570173
I am trying to find a stage that can be positioned along any planar axis of rotaion through its center. Like a plate riding on top of a hemisphere. The stage needs to be controllable though, either with micrometers or some other method. It can also be controlled through servos or some other electro-mechanical means. The stage needs to be at least 3" square (or diameter) and no larger than 4" square (or diameter). Thanks for your help

Let's confirm: You need to rotate your sample - the thing you want to position with your stage - about 2 mutually perpendicular axes. The axes of rotation intersect. The sample will be a distance D from the intersection of these axes. Over what range of the 2 angles do the sample need to rotate? Do you need to measure the angles? What is the smallest change you need to make in each of the angles? What does the sample weigh?
