Embodiment Construction

[0032] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0033] The core idea of ​​the present invention is that a plurality of spherical grooves are arranged on the back of the mirror carrier, and adjusting screws with spherical ends are used, and the adjusting screws enter the optical engine from the outside of the lower shell of the optical engine through the adjusting screw holes on the lower shell of the optical engine and then against the first spherical groove on the back of the mirror ...

Abstract

The invention discloses a reflector adjusting device which is capable of realizing the technical effect of precise reflector position and / or angle adjusting. The reflector adjusting device comprises a reflector, a reflector carrier, an optical engine lower housing, a plurality of adjusting elastic sheets and a plurality of adjusting screws. The reflector is fixed on the front side of the reflector carrier. The back side of the reflector carrier is provided with a plurality of spherical grooves. One end of reach adjusting elastic sheet is clamped to the reflector carrier, and the other end is fixed on the optical engine lower housing. The optical engine lower housing is provided with a plurality of adjusting screw holes corresponding to the plurality of spherical grooves in the back side of the reflector carrier. The heads of the adjusting screws are spherical ends, and the adjusting screws penetrate through the adjusting screw holes of the optical engine lower housing to enable the spherical ends to be abutted in the spherical grooves of the optical engine lower housing. The contact mode between the each spherical end and each spherical groove enables that tangential stress and normal stress of the contact position are very small, and the fine adjustment of the position and / or angle of the reflector is facilitated.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a mirror adjustment device. Background technique [0002] In the use of optical instruments, the mirror mainly plays the role of turning the light beam to realize the change of the optical path, and its installation, fixing and adjustment all play an important role. During the adjustment process of the reflector, the adjustment of its inclination angle will cause the position of the central light reflection point to change, resulting in the change of the front and back distance of the central light reflection point, resulting in a shift of the local optical path and reducing the light efficiency. [0003] Such as figure 1 As shown, it is a schematic diagram of the laser light source reflector with the upper casing of the optical engine removed in the prior art. The laser beam is converged by the first lens 101 to the reflection mirror 103 fixed on the lower case 102 of the opt...
