Abstract
An optical device includes a stack having a transparent block with a rear face fixed on a front face of an integrated chip support. A front face of the transparent block that is parallel to its rear face is affixed to a rear face of a converging lens. The lens has a convex frontal surface. A diaphragm is interposed and fixed between the block and the lens. A housing for the optical device is made of an opaque material. A peripheral wall of the housing encloses the stack. An annular front part of the peripheral wall bears on a periphery of the convex frontal surface of the lens so as to define a frontal opening located in front of a central part of the lens.
