消色差的

Their first model was TS-65 a 65mm x 900mm achromat.

他们的第一款产品是TS-65，65mmx900mm的消色差望远镜。

As for the compensator,it is characteristic of convenient adjustment, big adjusting range and high degree of accuracy. The theory and experiment show that the most important feature of this composite compensator is its achromaticity in a certain spectral range.

本文在复合式补偿器研究基础上，进一步从理论和实验上证明了该补偿器不仅具有相位补偿性能，而且在一定的光谱范围内满足消色差性能，削弱了延迟量对波长的依赖关系，适合于复色光使用。

The theory and experiment show that the most important feature of this composite compensator is its achromaticity in a certain spectral range. the compensator can be used to polychromatic light because its retardation is independent of wavelength.

本文在复合式补偿器研究基础上，进一步从理论和实验上证明了该补偿器不仅具有相位补偿性能，而且在一定的光谱范围内满足消色差性能，削弱了延迟量对波长的依赖关系，适合于复色光使用。

So the theoretical basis is provided for optimizing achromatism of the rhomb-type retarder and the material selecting scope can be extended.

从而为优化菱体型相位延迟器的消色差性，扩大材料的选取范围提供理论指导。

Through the further research to the theory of the high-accuracy achromatism phase retarders,the changing curve of retardation under the different center refracting rate and different precision are obtained.

通过对高精度消色差相位延迟器理论设计的再研究，分别得到在不同中心折射率下和不同延迟精度下，延迟量随折射率改变的变化曲线。

As a result of technologies developed during World War II, advances in apochromatic lens design got a big boost.

作为在第二次世界大战期间开发的技术，复消色差透镜的设计又有了大促进。

Finally,design example of apochromatic telephotolens is given.

最后给出了运用这种方法进行的摄远型透镜组的复消色差设计。

Apochromatic refractors are available with objectives of up to 553mm in diameter, but most are between 80 and 152mm.

高度消色差折光镜的口径已经可以做到553毫米的直径，但多数仍在80～152毫米之间。

CaF2 optical crystal in which other materials are unable to replace manufacturing Apochromatic lens of the main materials.

其中CaF2光学晶体是其他材料无法取代的制造复消色差镜头的主体材料。

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。
