消色差的

The request for exit pupils as large as 7.1mm leads to either small fields of view or, if an apparent field of 60 degs. or more is wanted, to a sophisticated design with either huge prisms or semi-apochromatic objectives.

大到7.1mm的出瞳直径的需求，导致要么是小视野；要么是：如果表现视场想达到60度或更大，老练的设计是需要巨大的棱镜或半消色差物镜。

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。

According to thin film polarization effect and eigenmatrix,the Fresnel retarder s achromatic width is expanded by evaporating dielectric membrane in two total-reflection surfaces of the rhomb.

根据薄膜的偏振效应，从薄膜的特征矩阵出发，通过在菱体的两个全反射面蒸镀光学介质膜的方法拓宽了菲涅耳菱体型相位延迟的消色差宽度。

Graduate University of the Chinese Academy of Sciences, Beijing 100039, ChinaThe partial dispersion of some typical glasses working on near infrared band was calculated with the formulas in which P and V were modified. The apochromatism of a wide band system was designed and analyzed.

利用修正的部分色散和阿贝数公式，计算一些典型的普通光学玻璃在450nm～950nm波段的色散特性，应用二级光谱理论，采用普通光学材料，设计了一个复消色差系统，分析近红外波段光学系统的二级光谱特性及校正方法，给出设计实例。

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。

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。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

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。
