Patent attributes
An optical system includes a lens cell 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 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 has a generally cylindrical body with the sleeve at least partially inserted into the housing. A clip 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 is releasably coupled to and inserted through the housing and into the sleeve to restrict rotation of the sleeve relative to the housing.
