[0002] Optical glass is a glass that can change the propagation direction of light and the relative spectral distribution of ultraviolet, visible or infrared light. In a narrow sense, optical glass refers to colorless optical glass; in a broad sense, optical glass also includes colored optical glass, laser glass, quartz optical glass, radiation-resistant glass, ultraviolet infrared optical glass, fiber optical glass, acousto-optic glass, magneto-optic glass and photochromic glass. Optical glass can be used to manufacture lenses, prisms, reflectors and windows in optical instruments. Components made of optical glass are key components in optical instruments. During the processing of optical glass, it is necessary to use a fixture to clamp and fix it for processing. After searching: A fixture for an optical glass side grinding device with a publication number of CN217255200U includes: a support seat, a positioning seat, a clamping block, a telescopic drive mechanism and a measuring mechanism; the measuring mechanism includes a measuring shaft, a measuring plate, a limiting wheel, a measuring ring, and a measuring block. One end of the measuring shaft is fixedly connected to the measuring plate, and the other end of the measuring shaft is fixedly connected to the center of the limiting wheel.
