消色差透镜

An achromat is a lens consisting of two cemented elements made of different materials, usually flint glass with crown glass. The achromat offers superior correction of spherical aberration in monochromatic applications.
In addition to higher image quality, additional advantages of the cemented achromat include: simplified mounting since it becomes one unit, smaller light loss resulted from fewer surfaces, less stray light due to reduced reflections.
