Abstract: An optical device includes a housing enclosure, a lens cell holder mounted to the housing enclosure by a retainer, a lens assembly mounted to the lens cell holder such that the lens assembly is configured to translate in an axial direction; and a radial space defined between the lens cell holder and the retainer that is sized to accommodate adjustment of the lens cell holder and the lens assembly in a radial direction with respect to the housing enclosure. A method of adjusting a line of sight of the optical device includes (i) positioning the lens assembly against the housing enclosure; (ii) adjusting the radial position of the lens assembly until a pre-determined line of sight requirement is achieved; and (iii) fixing the lens assembly to the housing enclosure of the optical device to preserve the radial position of the lens assembly with respect to the housing enclosure.
