Agreed, aligning it could be tricky. The linear is also truth.

It also have a great advantage. You could place it at the bottom of a long stick, and still have precision, while pots moving in a very short arc are far less reliable.

To achieve that kind of precision with optics, you will need some demultiplying system.

Now... so much precision got a draw back, filtering is MANDATORY!
