<p>An adjustable pad assembly (70) is used for aligning a polygon of an optical system that is supported by a housing (14) and requires precise alignment with respect to a base (52) for proper operation of the optical system. A plurality of the adjustable pad assemblies are located between the base and the housing. Each pad assembly includes a mounting plate (72), and a bushing (76) that is secured to the housing. A compressible ring (74) surrounds a surface on the plate that receives an adhesive (90). The housing is adjusted relative to the base to align the polygon, and then held stationary until the adhesive cures to bond the mounting plate and bushing together. <IMAGE></p> |
