Study on Ultra-Turning Technology of Optical Chalcohalide Glass Using Diamond Tool
Chalcohalide glasses become ideal infrared optical fiber materials because of its isotropy, homogeneousness and high transmittance in visible and infrared region. This paper reported an experimental study on micro aspherical lens using ultra-precision single-point diamond turning technology. Turning test of a GeSe2 sulfur-base glass aspheric lens using form error compensation technique is conducted and investigated in turning process. The experimental results show that micro aspheric lens surfaces with form (PV) around 0.167 µm and a roughness (Ra) less than 2 nm is achieved successfully.
