Lower Beam Height

**wondertwnz** · 11-22-2011, 08:54

Any suggestion for a mirror mount or other method to lower a beam from a laser by 25mm
Trying to match some lasers and do not have enough space for a very large mirror assembly hoping there might be some other optics options I do not know about?
thanks

Perhaps a long slotted "L" bracket with 2 MM1's attached?

Very limited on space and not sure I can make that fit. I am looking at some right angle prisms maybe

does this make sense ( beam enters from left, jogs down, exits right) It is a 45 degree slot machined in a block and a mirror mounted on each face..i used to make these for the big yags...i called them beam joggers..hope the drawing makes sense.

OH CRAP...when i hit return it screwed up the drawing...sorry....
looks goood before i post

Have you considered an AR coated rhomboid prism? They're a great way to easily achieve accurate beam displacement.
