FIELD: optics. ^ SUBSTANCE: optical targeting device for day and night observation consists of collimator system in form of two-les glued objective, made in form of negative and positive quasi-focal meniscuses, directed by concave surfaces to one another, light-splitting cube, positioned behind second positive meniscus, and light source, positioned outside optical axis. On concave surface of first from object negative meniscus, interferential spectrum-splitting cover is positioned. Light-splitting cube is glued together of two same prisms with interferential spectrum-splitting cover on glued hypotenuse side of one of prisms. One of leg sides of first prism along beams way is perpendicular to optical axis and directed towards objective, and close to second side light source is positioned. Relations displayed in formula of the invention are fulfilled by described device. ^ EFFECT: higher image quality, no parallax, decreased dimensions and simplification of construction. ^ 3 dwg |
