消色差

The main advantage of reflecting telescope there is no chromatic aberration, when the objective lens when using parabolic, but also can eliminate spherical aberration.

反射望远镜的主要优点是不存在色差，当物镜采用抛物面时，还可消去球差。

of designing an achromatic lens with F/#=1 and aperture D=5mm is developed and numerical simulation is performed.

利用这种特性，本文提出了一种变深度亚波长孔阵金属折衍混合透镜（DV- SHAM R/D lens），它是由DV- SHAM lens与折射透镜结合，能够消色差，实现宽波段成像。

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。

To avoid the shortcoming of magnification change with wavelength, which will cause the spectral image pixel registration error and provide inaccurate relative spectral signal strength in the classical diffractive optic imaging spectrometer, a novel hybrid refraction/diffraction telecentric optical system combining a diffractive lens with an achromatic lens system is presented, and the working principle is then established.

为了克服在传统衍射光学成像光谱仪中，衍射透镜的焦距随波长变化引起系统放大率随波长变化，从而导致光谱图像的像元配准误差，得到并不精确的相对光谱信号强度，提出了将衍射透镜与消色差透镜系统相结合的新型折/衍混合、二组元复合远心成像光学系统的技术方案，具体分析推导了该系统的成像理论。

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 ''.

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''。

Radiation from a fiber coupled diode (core diameter 0.4 mm, N.A. 0.3) is coupled into Tm5% at.,Ho(0.5% at.∶GdVO4 crystal by a pair of achromatic lens for end pumping. Output power of 3.6 W at 2.048 μm is obtained under pump power of 14 W and emission wavelength of 794 nm. The optical-optical conversion efficiency is 25.7% and slope efficiency is 26.6%.

在液氮制冷晶体条件下，利用光纤耦合激光二极管及消色差光学耦合系统端面泵浦双掺5％Tm，0.5％Ho∶GdVO4晶体，在泵浦功率14 W、泵浦波长794 nm时，实现了2.048 μm激光输出，连续运转输出功率3.6 W，相应的光光转换效率为25.7％，斜率效率26.6%。

Featuring wider angle views than predecessors, a new "super achromatic" objective lens,"Phase Corrected" Abbe-Koenig prisms, light transmission of at least 91%, and nitrogen filled composite housings reinforced with fiberglass to assure high endurance. In September 1994 Zeiss announced the first "Contax" 35mm rangefinder camera with interchangeable lenses made since 1959; the "G1" features include auto focus with any of four optional lenses, TTL metering, automatic film advance of up to 2 frames per second, and a luxurious titanium body.

这些新品体现了公司技术成就的最新进展，拥有较以前产品更宽的视角，新型&超消色差&物镜，&相位修正&阿贝-科宁棱镜，至少91%的透光率，充氮加固玻璃纤维复合镜室，以确保产品的耐用性。1994年9月，蔡司又推出了自1959年以来的首款镜头可互换型&康泰克斯&35mm连动测距对焦相机；此款&G1&型相机包括自动对焦功能和可任选的四个镜头，晶体管逻辑电路测距（TTL，晶体管逻辑电路），每秒高达两帧的自动卷片功能，和豪华钛机身外壳。

On 24 June 1904 the issuing certificate for a new Zeiss trademark was issued; this logo was fashioned with "Carl Zeiss" within in the border of an achromatic doublet lens outline designed by a consultant Erich Kuithan b.

1904年6月24日，蔡司公司的新商标得到了确认。商标图案是一片消色差双合透镜外轮廓线，里面套着&Carl Zeiss&字母，由公司顾问埃瑞克库森（Erich Kuithan，1875年生，卒于1917年）设计。
