非球面透镜的优点
在需要较大接受角(例如收集光线用于照明)的应用中,由于球面像差的存在或球面折射的作用随着孔径而增加,使得球面透镜不适用。非球面透镜保持恒定的焦距或非常高的 NA,因此无需多个元件来校正球面像差。这样通过减少重量和组件数量简化了系统设计。同时还可实现更少的透射损耗,并且由于具有更少的表面数量而减少了重影。非球面透镜的主要缺点是离轴性能差。这对于光耦合进/出光纤或准直光源并不是问题,但是非球面镜在较宽视野中不可用。
Molded Glass Aspheric Construction
These Geltech lenses are made from Corning C0550 glass, which features low dispersion (Vd=50.40). Typical applications include fiber coup领, laser diodes, medical lasers, optical data storage, and barcode scanners. Mounted versions with a 304 stainless steel holder are also available.
