FIELD: means for checking the sights designed for teleorientation of vehicles, in particular, of flight vehicles using injection lasers as sources of radiation.
SUBSTANCE: a limiter of the diameter of the bundles of rays is additionally installed in alignment with the eye-piece optical axis in the eye-piece with an eye-shield of the sighting channel. The limiter mentioned above is shifted in the axial direction by the eye-piece diopter device until a clearly defined image of the diaphragm reticule is obtained. The limiter of the diameter of the bundles of rays is made in the form of a sleeve with a central hole in the bottom and a reduction in the outside diameter at the end face. The sleeve is installed by the reduction in the body in alignment with its optical axis, ad by the outside diameter - in the inside diameter of the eye-shield made formed to shape. The distance between the sleeve bottom and the eye-shield is equal to the distance between the last lens of the eye-piece and the entrance pupil of the sight.
EFFECT: enhanced accuracy of measurement of the sight parameters.
