Problems solved by technology

Considering that in actual engineering, the component is assembled horizontally and used sideways, the eccentricity and tilt of the lens are poorly controllable, and the assembly of each spring is inconvenient during integration. It is often suitable for testing and is not conducive to engineering

Abstract

The invention provides a side-mounted lens set and a mounting method thereof. The lens set comprises a frame, an optical lens and two hard supporting points which are symmetrically distributed at two sides of the vertical axis of the frame and are integrally formed with the frame, wherein each hard supporting point directly contacts with and is connected with the optical lens. The bottom of the optical lens is provided with an elastic supporting member in contact connection through an adjusting screw. The top of the frame is provided with a compression screw which is used for preventing axial displacement of the optical lens. The mounting method comprises the steps of placing the optical lens on the hard supporting member of the frame sideways; applying a force with a certain magnitude to the optical lens through the compression screw for making the optical lens abut against each hard supporting point; adjusting the supporting force of the elastic supporting member for supporting the optical lens, and locking the adjusting screw; mounting more than one pre-tightened reed, applying glue to glue applying holes for fixedly connecting the frame with the optical lens; and mounting an axial stopper. The side-mounted lens set and the mounting method have advantages of relatively high stability, relatively high face type precision and benefit for engineering realization.

Description

technical field [0001] The invention relates to a mirror group, in particular to a side-standing mirror group and an installation method thereof. Background technique [0002] The processing and manufacturing of high-precision optical lenses is a very complicated process. As the imaging quality of the optical system becomes higher and higher, not only the optical path becomes more and more complicated, and the number of optical components increases, but also the optical components are required to have micron-scale Positioning accuracy, while maintaining surface accuracy of ten nanometers. [0003] In catadioptric lenses, the optical axis not only has a vertical direction, but also a horizontal direction, that is, the optical element needs to be installed sideways in addition to being installed horizontally. The effect of gravity on optical elements placed horizontally is completely different from that on optical elements placed sideways. When the diameter of the optical ele...
