Abstract

The invention discloses a processing method of a plane convex cylindrical mirror. The processing method comprises the following steps that a glass blank material is coarsely ground into a cylinder; then, fine grinding and polishing are sequentially performed on the cylinder surface, so that the radius of the polished cylinder is in the radius requirement range of the plane convex cylindrical mirror; the polished cylinder and a plane mold are cast into a dish; the excessive cylinder surface of the cylinder is ground and cut into a plane along the axial direction of the cylinder to form a primary sample of the plane convex cylindrical mirror; the primary sample of the plane convex cylindrical mirror is demoulded; then, the plane of the primary sample of the plane convex cylindrical mirror is ground and polished, so that the arc height of the polished primary sample of the polished plane convex cylindrical mirror is in the arc height requirement range of the plane convex cylindrical mirror; the two ends of the polished primary sample of the polished plane convex cylindrical mirror is subjected to end surface grinding to obtain a finished product of the plane convex cylindrical mirror; the length is in the length requirement range of the plane convex cylindrical mirror. The processing method provided by the invention solves the problems of low precision and low efficiency of the existing processing method of the plane convex cylindrical mirror, and has the advantages that the universality is high; the dimension control precision is high; the mass processing of the plane convex cylindrical mirror can be realized.

Description

Technical field [0001] The invention relates to the field of optical parts processing, in particular to a processing method of a plano-convex cylindrical lens. Background technique [0002] Plano-convex cylindrical mirror is an optical conversion element that can transform a point light source into a line light source, and is widely used in optical instruments, photoelectric sensors and other fields. With the advancement of science and technology, aerospace, optics, electronics and other high, precise and sharp fields have higher and higher requirements for the processing of plano-convex cylindrical mirrors. For example, ordinary plano-convex cylindrical mirrors require arc height differences at both ends It is less than 0.020mm, and the high-precision plano-convex cylindrical mirror requires the arc height difference at both ends to be less than 0.003mm. The arc surface and the plane surface shape, the arc height and the consistency of the arc height at both ends are the key in...
