OPTICAL SIGHT Russian patent published in 1997 - IPC

FIELD: devices for optical laying and sighting, can be used for sight laying mainly of sporting arms. SUBSTANCE: optical sight has the first telescopic channel formed by a positive lens and a negative eyepiece with matched focuses in the space of the exit pupil, semitransparent plate, sighting mark collimator including a diaphragm and collimating lens, and the second telescopic channel optically conjugate to the collimator and formed by the positive component and eyepiece, whose focuses are matched in the space of the exit pupil. For lighting the diaphragm (sighting mark) use is made of the light running on the side of the objects of observation, or light from an artificial source. The focal length of the lens exceeds the focal length of the eyepiece, the semitransparent plate is positioned in the middle area of the air gap, magnification of the second telescopic channel is lower than that of the first channel. EFFECT: enhanced convenience in use. 2 cl, 1 dwg
