ABSTRACT:
An optical assembly includes an optical collimator having an outer periphery and an optical-path end opening. A collimator beam-path axis extends through the optical-path end opening. The optical assembly further includes a hollow bonding sleeve having a sidewall having an inner periphery receivable over and affixed to the outer periphery of the optical collimator, an endwall having an aperture therethrough in facing relation to the optical-path end opening of the optical collimator; and an optical device in registry with the aperture of the endwall and affixed to the endwall. To fabricate the optical assembly, the optical collimator and the bonding sleeve are separately prepared, the optical device is affixed in registry with the aperture of the endwall, the bonding sleeve is assembled to the optical collimator, the optical device is aligned with the collimator beam-path axis, and the bonding sleeve is affixed to the optical collimator.
