A single point diamond turning technique for optical crystals is reported in this paper. The main factors influencing the machined surface quality are discovered and the regularities of the machining process are drawn. A new parameter Rs is introduced to evaluate the surface quality of diamond turned optical crystals. Under the optimized machining conditions, mirror surface of roughness value Ra 0.006 μm is obtained on single crystal germanium.
