Hi,
I have a train of plane mirrors which will be used to relay a laser beam in a folded path. For that the mirrors has to be aligned at an incidence angle of 45 degree - means each mirror will be perpendicularly aligned to each other one after another.
The one way to achieve this alignment is by using the autocollimator with an specially designed prism window. For this method see this link: <http://www.techbriefs.com/component/content/article/2963>
Can there be any other way more sophsticated to achieve alignment with micro radian accuracy? Can anybody help me out? Thanks in advance.
