OPTICAL SIGHT Russian patent published in 2005 - IPC

FIELD: optoelectron instrument engineering, in particular, structural members of protection of sighting devices.

SUBSTANCE: at least a portion of the image of the sight mark, or of the sight mark and the sight scale in the sight is formed by structures at least of the same identical type built up on the face surface of the optical member. The mentioned structures have side surfaces forming cavities in the optical member with a fine-pointed and or rounded off crown each. Besides, the mentioned image may be formed by structures at least of the same identical type with a fine-pointed and/or rounded off crown each, positioned for formation at least of portion of the image of the sight mark, or of the sight mark and the sight scale.

EFFECT: enhanced efficiency of masking of the optical sight by increasing the range of deflection of the pilot radiation in case of variation of its characteristics.
