Abstract
An optical sight for a combat vehicle, intended to be mounted in a weapon turret of the vehicle in order to make possible sight lines at elevations between roughly −10° and 90° of a weapon barrel mounted pivotably about a horizontal axis in the weapon turret. The sight comprises a lower standard sight unit, which deflects vertical incident light by 90° to an eyepiece, and a top mirror, located above the standard sight unit and pivotable in synchronism with elevating movements of the barrel, likewise about a horizontal axis. Positioned above the standard sight unit is a deflection prism which has an upper surface which faces the top mirror, is inclined at roughly 45° to the vertical and is designed to reflect incident light at an angle of roughly 45° to the surface and less, but to transmit light which is incident at roughly 90° to the surface.
