Collimators and auto-collimators for levelling and aligning

[daveykbelgium]

Can anybody guide me on whether it is possible to level and align a number of modules very accurately - say 0.05mm - using a collimator or auto collimator.

Many thanks

Dave

Autocollimators align to angles, not distances. 1 urad should be achievable:
