Abstract
An opto-mechanical device, such as a lens cell, includes a housing having an axially extending chamber and an intermediate internal spacer that positions a sharp-edged lens in the chamber. The sharp-edged lens has first and second optical surfaces that intersect in a circumferential sharp edge. The housing positions an image sensor proximal to the sharp-edged lens for processing light therefrom.
