消色差的

They are designed to bring three wavelengths into focus in the same plane. The residual color error can be up to an order of magnitude less than that of an achromatic lens.

他的设计能让三种不同的颜色(通常是红色、绿色和蓝色)汇聚在相同的焦平面上，颜色的残差错误比消色差透镜少了一个数量级。

The general condition for athermalzing an optical system when the object surface is at finite or infinite distance is deduced in this paper, and the principle and design method of employing a diffractive optical element to athermalize and achromatize an optical system with normalized T-C chart are expounded.

本文推导了物面位于有限和无限距离时实现光学补偿的通用条件，论述了利用归化T-C图设计热补偿和消色差红外光学系统的原理和设计方法，给出了8-12μm波段内、焦距123mm、相对口径F/2.5在20-60℃温度范围内的折衍混合红外光学系统的设计结果和理论评价结果，所述的设计方法可方便地推广到前视红外系统中。

Lens: Our exceptional, multi-coated triplet, air-spaced apochromat uses the latest in multi-coating technology with the highest grade of optical glass to achieve exceptional image brightness and excellent color correction.

镜头：我们的例外，多层镀膜三重，空气隙的复消色差透镜采用最新的多与光学玻璃档次最高的镀膜技术，实现出色的图像亮度和出色的色彩校正。

An optical system of measuring system is constituted by a illuminating system and a magnifying system. The illuminating system adopts a far center illuminating mode to make the illumination unified. The magnifying system all adopts object far center optics path to eliminate the error for out of focus. The objective is a plan and apochromat to make image clear. The operator adjusts focus with parameters provided by computer.

论文分析了纤维细度测量系统的光学系统：照明系统采用远心柯勒方式，实现物面的均匀照明；成象系统采用物方远心光路，减少离焦对纤维细度测量的影响；物镜采用平场消色差物镜，消除因为象差引起的图象变形和不清晰，为纤维细度的高精度测量奠定基础；在图象清晰度判别中采用计算机计算参数结合人工调整的方法，既保证结果的客观性，又使系统简化。

Of course, apochromatic correction of lenses is not something that you expect the average engineer to be familiar with, but we're talking here about a group of optical design specialists.

当然，镜头的复消色差并非普通工程师必须熟悉的，但是，我们讨论的是一群光学设计的专业人士。

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。
