Abstract
Disclosed is a method and apparatus for the lowcost assembly of precision optical devices utilizing single or multiple bounces. The apparatus makes use of a precision machined alignment platform to support optical mirrors in precise alignment. A low cost holding structure is clamped over the alignment platform to position one of a plurality of connected sections adjacent to the back of each mirror. An adhesive is injected through holes provided in the holding structure adjacent to the back of each mirror. The adhesive bridges each mirror to the holding structure in a position corresponding exactly to the position of the mirrors on the alignment platform, thereby eliminating any need to adjust the mirrors for correct alignment.
