Abstract:
1. An optical system comprising: a lens cell having a generally cylindrical lens cell body and an optical lens system therein, wherein 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 having a generally cylindrical sleeve body, wherein the sleeve body has an outer surface with a first longitudinal axis and an inner surface with a second longitudinal axis eccentrically offset from the first longitudinal axis, wherein the lens cell is inserted into the sleeve; a housing having a generally cylindrical body, wherein the sleeve is at least partially inserted into the housing, and a clip disposed about at least a portion of the circumference of the housing, wherein 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, and wherein, 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, and the clip comprises an elongated curved body with a first end and a second end, and having a tab extending from each end thereof, the tabs being sized to engage the sleeve through the housing.
