ABSTRACT:
The invention relates to an episcopic sight usable for observation and firing by day or night on a vehicle equipped with a gun. The sight includes an assembly of interchangeable moduli grouping the optical elements, particularly made of a head modulus 1 containing a mirror controlled in elevation, a height increase modulus 2, a day sight modulus 4, a night sight modulus 5, a rangefinder modulus 6, an electronic case associated to a fire-control computer. It includes a modulus of separation 3 of the day and night channels interposed between the height increase modulus 2, and the day and night moduli 4, 5, the modulus of separation 3 containing the means for generating a sight reticle in the day and night channels. The means of generating a firing reticle include a projection collimator of this reticle and a rhombohedron to inject this reticle into the day and night moduli.
