Abstract:
1. A selectively mountable optical assembly, comprising: an optics body comprising a first end, a second end opposite the first end, a tubular body portion, a longitudinal passage extending along a longitudinal axis between the first and the second ends and through the tubular body portion, and at least two lugs proximate to the second end and extending radially therefrom; at least one optical element received in the longitudinal passage of the tubular body portion; a mounting base having an interior surface that forms an interior passageway with at least two notches, the interior passageway having a longitudinal axis, the at least two notches sized and positioned to receive respective ones of the at least two lugs at a same time, when the longitudinal axes are coaxial and the optics body is in a first angular position about the longitudinal axis of the interior passage with respect to mounting base; wherein mounting base further comprises at least one engagement surface positioned to securingly engage at least one of the lugs when the optics body is in a second angular position rotated about the longitudinal axis of the interior passage with respect to the first angular position, wherein the optics body farther comprises a radial flange proximate the second end; and wherein the radial flange has a plan view profile of a first non-circular geometrical shape and wherein the mounting base has a plan view profile of a second non-circular geometrical shape, where the first and the second non-circular geometrical shapes are the same non-circular geometric shapes.
