Binoviewer (original) (raw)

A binoviewer is an optical device designed to enable binocular viewing through a single objective. In contrast to binoculars, it allows partially stereoscopic viewing and partially monoculair viewing, this because the eyes and brain still process the image binocularly, as both images are produced by the same objective and do not differ except for aberrations induced by the binoviewer itself. Binoviewers are a standard component of laboratory microscopes and are also used with optical telescopes, particularly in amateur astronomy. * v * t * e
