Collimated optical system with clip ring locking mechanism

摘要

An optical system includes a lens cell (150) having a generally cylindrical lens cell body. The lens cell body has a lens cell central longitudinal axis and a lens cell optical axis eccentrically offset from the lens cell central longitudinal axis. A sleeve (130) includes a generally cylindrical sleeve body having an outer surface with a first longitudinal axis and an inner surface with a second longitudinal axis eccentrically offset from the first longitudinal axis. The lens cell is inserted into the sleeve. A housing (110) has a generally cylindrical body with the sleeve (130) at least partially inserted into the housing. A clip (118) is disposed about at least a portion of the circumference of the housing. The lens cell and the sleeve are rotated relative to each other and to the housing such that the lens cell optical axis is aligned in a desired location. After the lens cell optical axis is aligned in the desired location, the clip (118) is releasably coupled to and inserted through the housing (110) and into the sleeve (130) to restrict rotation of the sleeve relative to the housing.
