Adjusting device for reflector

Abstract

The invention discloses an adjusting device for a reflector, which comprises the reflector, a reflector carrier, a plurality of adjusting elastic sheets, a lower optical engine shell, a plurality of adjusting springs and a plurality of adjusting bolts, wherein the reflector is fixed on the front surface of the reflector carrier; a plurality of bolt pillars are arranged on the rear surface of the reflector carrier; one ends of the adjusting elastic sheets are in blocking connection with the reflector carrier while the other ends are fixed on the lower optical engine shell; a plurality of adjusting bolt holes corresponding to the bolt pillars are arranged on the lower optical engine shell; a plurality of spring slots around the adjusting bolt holes are arranged on the back side of the lower optical engine shell; the adjusting bolts pass through the adjusting bolt holes and are connected with the bolt pillars of the reflector carrier; the adjusting springs are around screw rods of the adjusting bolts; and one ends of the adjusting springs are resisted against the spring slots of the lower optical engine shell while the other ends are resisted against the nuts of the adjusting bolts. The adjusting device for the reflector provided by the invention can be used for conveniently adjusting the position and / or angle of the reflector.

Description

technical field [0001] The invention relates to an optical element adjustment technology, in particular to a mirror adjustment device. Background technique [0002] Reflector is an important optical component, which occupies a very important position in optical instruments. At present, in the use of optical instruments, the main function of the mirror is to realize the turning of the light beam and the change of its direction. Therefore, the installation, fixing and adjustment of the mirror all play a very important role. However, during the adjustment process of the reflector, the adjustment of the inclination angle of the reflector will often cause the position of the central light reflection point to change, resulting in changes in the front and rear distances of the central light reflection point, resulting in a shift in the local optical path and reducing light efficiency. .

AI Technical Summary

Problems solved by technology

However, in this reflector adjustment device, since the adjustment structure makes the reflector fixed on the reflector base rotate around the pillar and tilt around the bottom of the second side wall, the translation of the reflector along the normal direction cannot be realized. , so it is also difficult to easily adjust the position and / or angle of the mirror
