氟化鈣平凸透鏡
CaF2 Plano convex Lenses are made from CaF2 material. They present a curvecd interface and a planar interface. They have a positive focal length, which makes it ideal for collecting and focusing light for many imaging applications. They are for instance the microlenses situated on top of a wafer, and also encountered in macroscopic optical systems.
