Plane upper disc die for plano-convex lens

The utility model relates to the technical field of lens processing auxiliary equipment, and discloses a plano-convex lens plane upper disc die which comprises a disc-shaped body, the disc-shaped body has a certain thickness, a plurality of stepped holes are formed in the upper surface of the disc-shaped body, the stepped holes are formed in an annular array of a plurality of concentric circles, and the thickness of the stepped holes is larger than that of the disc-shaped body. The aperture of an upper hole of the stepped hole is matched with the diameter of the plano-convex lens, the aperture of a lower hole of the stepped hole is smaller than the diameter of the plano-convex lens, and the annular shoulder part of the stepped hole is used for being matched with the convex surface of the plano-convex lens. According to the utility model, the convex surface of the lens is fixed, the plane is polished, and the processing of the lens is completed. 本实用新型涉及透镜加工辅助设备技术领域，公开了一种平凸透镜平面上盘模，包括盘状本体，所述盘状本体具有一个厚度，盘状本体的上表面上布
