The invention relates to an optical sight for a combat vehicle, intended to be mounted in a weapon turret (26) of the vehicle in order to make possible sight lines at elevations between roughly -10 DEG and 90 DEG of a weapon barrel mounted pivotably about a horizontal axis in the weapon turret. The sight comprises on the one hand a lower standard sight unit (12), which deflects vertical incident light by 90 DEG to an eyepiece (16), and on the other hand a top mirror (18), located above the standard sight unit (12) and pivotable in synchronism with elevating movements of the barrel, likewise about a horizontal axis. Positioned above the standard sight unit (12) is a deflection prism (20) which has an upper surface (22) which faces the top mirror, is inclined at roughly 45 DEG to the vertical and is designed to reflect incident light at an angle of roughly 45 DEG to the surface and less, but to transmit light which is incident at roughly 90 DEG to the surface (22). The mirror (18) is arranged so as to direct incident light parallel to the barrel essentially at right angles to the upper surface (22) of the prism (20), so that the incident light, after reflection against a surface (24) lying behind, can be reflected from inside against the upper surface (22) in order then to be made to fall vertically into the standard sight unit (12). <IMAGE> |
