锗透镜 meaning in English

germainium lens

Because it ' s good capability in refracting infrared ray , ge lenses was widely used in infrared optical system
这对国内小型非球面加工研究是很有意义的。红外系统中非球面锗透镜应用普遍。
In the paper , the testing scheme and making of a aspheric ge lens that used in planar wide - angle altazimuth was described
就平面广角地平仪设计中用到的一块非球面的小型锗透镜作了检验设计和加工。
E . g . the ge lens used in planar wide - angle altazimuth , indirect ophthalmoscopy lens in ophthalmic diagnosis , zoom lens of camera , all were minor aspheric component
例如，红外广角地平仪中的锗透镜、眼科诊断用的间接眼底镜、变焦照相机镜头、刻录机光头等都是小型的非球面元件。
Surrounding with the subject of minor asphere making and test , we pursued work in four side : the design , test and making of aspheric indirect ophthalmoscopy lenses , test and making of aspheric ge lens , double asphere lens testing , study on testing of refractive convex aspheric surface
本文围绕小型非球面检验加工这个课题，主要做了四个方面的工作：非球面眼底镜的设计、加工和检验，非球面锗透镜的加工检验，双面非球面小型透镜检验方法的探讨，凸二次非球面检验方法的研究。
