Polishing method for high-rise deep-concave spherical lens

摘要: The invention discloses a polishing method for high-rise deep-concave spherical lens. When surface is polished, an elastic rubber cup used supporting the lens; and when of sphere protective layer filling are manufactured on polished surface, lens supported through layer. simple, reasonable convenient to implement; by adding layer, can be effectively in process, support with even stress achieved without independently customizing special cup, manufacturing cost greatly reduced. Meanwhile, machining two faces only one tool, so that procedure simplified, efficiency improved, rapid low cost.
