SIGHTING DEVICE AND METHOD FOR ADJUSTMENT OF PARALLELISM OF OPTIC AXES OF INFORMATION AND SIGHTING CHANNELS Russian patent published in 2002 - IPC

FIELD: optico-mechanical instruments, in particular, sighting devices of controlled armament as a component of an antitank missile complex. SUBSTANCE: sighting channel has an additional light filter with an ocular in the body, which is installed between the objective lens and the graticule perpendicularly to the optic axis of the sighting channel and fastened on a common post. Adjusting screws are used for adjustment. The method for adjustment of parallelism of the optic axes of the information and sighting channels consists in the fact that the additional adjustment of parallelism of the optic axes of the mentioned channels is accomplished by means of an additional light filter after attachment of the device components. The light filter is inclined in two mutually perpendicular planes relative to the optic axis of the sighting channel until parallelism of the optic axis of the information channel is ensured. EFFECT: enhanced quality of the device and its parallelism of the optic axes of the information and sighting channels after attachment and fixing of the device components. 2 cl, 3 dwg
