Abstract
A system for biocular viewing of a distant scene or object especially under daylight conditions comprises an objective lens which produces an initial image, one or two relay lenses with associated reflectors which produce from that initial image a pair of tilted images, and a biocular magnifying eyepiece lens through which an observer views so that each eye receives light from a respective one of the tilted images. The system can be incorporated in a combined day and night viewing system employing common objective lens and eyepiece lens components for the day and night viewing paths.
