Abstract

The invention discloses an integrated mirror surface processing assembly-free optical telescope and a processing method thereof. The integral mirror surface processing assembly-free optical telescopecomprises an integral primary mirror reflector, a secondary mirror reflector and a secondary mirror mounting frame. The secondary mirror reflector is fixedly connected with the secondary mirror mounting frame through screws and positioning pins, the secondary mirror mounting frame is fixedly mounted on the integral primary mirror reflector through screws and positioning pins, and the surface of the curved optical reflector is integrally machined through a diamond lathe. Complex and tedious structural adjustment and optical assembly and calibration processes are omitted through integral mirrorsurface machining in telescope manufacturing, the telescope structure can be made of the same metal material, the temperature application range is large. Meanwhile, the metal mirror is provided with the flexible installation groove, the influence of telescope machining stress and installation stress on imaging is reduced, and the imaging quality is high.

Description

technical field [0001] The patent of the present invention relates to an integral mirror-processing free-fitting optical telescope, in particular to an integral mirror-processing free-fitting double-reflection optical telescope based on a metal reflector and a processing method thereof. Background technique [0002] Compared with transmission telescopes, reflective telescopes are optical telescopes that use curved surfaces or a combination of curved and flat mirrors to reflect and converge light rays and form images after imaging. Reflective optical telescopes currently developed generally use optical materials such as quartz and silicon carbide as mirror materials, which are expensive, cumbersome in design, difficult in structural adjustment and optical adjustment, and the imaging quality will be greatly affected by installation stress. The scope of adaptation is small. With the continuous development of diamond turning technology for metal mirror processing and the advanc...
