消色差透镜

This research and development effort bore its first noteworthy fruit in 1886 when Zeiss marketed the first "aphochromate" microscope objectives; this apochromatic microscope objective offered superior quality. Employing "fluorspar" elements this was the first use of crystal in an industrial optical application.

这些研究和发展的努力在1886年结出了第一个果实，蔡司公司于当年推出了"aphochromate"显微镜即复消色差透镜显微镜；此种显微镜提供了出众的品质，其中萤石成分的使用是玻璃晶体在工业光学中的首次应用。

The lens system comprises four separated lens components, with three of them being subapertures. Two examples of apochromatic telescope are presented, both with the use of typical normal glasses, namely crown K9 and flint F5 glasses, and low-cost slightly anomalous dispersion glasses.

本文介绍了一种采用小异常色散玻璃复消色差的新型结构形式的光学系统，由四个分离的透镜组构成；给出了两个望远镜物镜设计实例，均使用价格便宜的非异常色散玻璃，校正了二级光谱、倍率色差，同时也校正了其他色差和单色像差。

Achromatic doublets are far superior to simple lenses because they are corrected for two color lines, specifically C 656.27nm and F 486.13nm.

消色差双合透镜的优势远远超过简单的透镜，因为有两条色彩线，特别是C 656.27nm和F 486.13nm。

A tube containing a convex achromatic lens at one end and a slit at the other with the slit at the focus of the lens; light rays leave the slit as a parallel beam.

一端包含一个凸起的消色差透镜另一端在镜头的中心有一个小切口的小管；光线通过小切口成为平行光线。

We use Welford's aberration equation to obtain the initial phase parameters of the diffractive surface of the designed hybrid achromatic lens.

复合透镜不同於传统折射透镜，它一面为传统折射透镜，另一面为绕射透镜；它不但可消色差及降低其他像差，在体积及重量的缩小上也有相当的成效。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
