Patent ID: 7633634

Claim:
A method for precisely assembling an optical module, the method comprising: a) providing a set of optical components including a plurality of beam shaping components for converting at least one initial shape in cross section of a laser beam to at least one desired shape in cross section and an optical mount for supporting the set of optical components; b) holding and locating the optical mount relative to a reference axis; c) holding the optical components in position relative to the optical mount during step b) wherein the positions of the beam shaping components are initial positions; d) directing a laser beam having the at least one initial shape at the set of optical components during step c); e) adjusting the initial positions of the beam shaping components to obtain final positions of the beam shaping components relative to the optical mount during step d) until the laser beam has the at least one desired shape; and f) fixedly securing the optical components to the optical mount wherein the optical mount supports and is fixedly secured to the beam shaping components in their respective final positions after step e) when the laser beam has the at least one desired shape.
