COLLIMATING SIGHT WITH LUMINOUS MARKER Russian patent published in 1997 - IPC

FIELD: optical instrumentation engineering, in particular, optoelectronic sights for small arms. SUBSTANCE: collimating sight has a casing accommodating a barrel with a spherical mirror, light source for producing the sight marker with adjustable luminance, adjusting screws acting on the barrel together with the springs. At a change of the spherical mirror angular position the light source remains fixed. To expand the sight operating range in the conditions of different illuminance of the target, a glass with a photochrome coating is installed before the spherical mirror. The luminance regulator and battery compartment with cells is installed in a common casing and arranged in the front part of the cell. EFFECT: improved design. 3 cl, 2 dwg
