色差

At the beginning of the century, the mathematics and physics relevant to traditional lens design were already pretty well established, and early designs like achromatic doublets and the Petzval lens had already been developed.

上个世纪初，传统镜头设计的数学，物理框架已经建立得比较完备。早期的设计，如消色差胶合透镜，Petzval镜头已经被发展的很好了。

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。

In this paper,we will give a few examples of geometric design by taking different size parameters into consideration.We have made the prisms and put them into the application of measuring the magneto-optical Kerr ellipticity with success.

在本文中，我们给出了具有这种结构的几何设计例子，还结合不同参量成功地设计研制了一个消色差的1／4波长延迟器，并应用于磁光材料的克尔效应测量中。

If ED glass is combined with Flint glass or Crown-Flint or other similar types, you will have more or less color error.

如果ed结合火石玻璃或冕牌-火石玻璃或其他类似型号你会有或多或少的色差。

Zonal chromatic aberration of the objective is 0.13 mm at focal length 800 mm,and the triplet combination of the fluorite glasses and some heavy flint type glass is effective to correct color aberrations.

结果表明，采用氟化物玻璃与重火石玻璃的三片式组合在短波红外段具有较好的消色差能力。

The merit of the invention are: 1 adopting free curved surface imaging method , three part reflection type Zernike polynomial free curved surface forms short focal distance bigger, relative apertures bigger fields of view angle imaging , rectifying optical aberration much better and its structure is simple; 2 adopting the reflection structure without optical lens, has removed the effect of various chromatic aberration , guarantee the imaging articulation; 3 adopt the design of short focal distance big fields of view angle, focal distance 8 - 15 mm, field of view angles 100 -135 degree, having 120 times multiplications under 250 mm imaging distance, having ultra-thin characteristic property; 4 adopting big relative apertures design ,the relative aperture is 2.0-2.4, having improved the illuminance of flat surface; 5 adopting image space telecentric imaging method , ensures that the image surface irradiance is homogeneous.

本发明的优点是：1采用自由曲面成像方法，三片反射式Zernike多项式自由曲面形成短焦距大相对孔径大视场角成像，更好地校正像差，结构简单；2采用无透镜形式的反射式结构，消除了各种色差影响，保证成像清晰度；3采用短焦距大视场角设计，焦距8～15mm，具有100～135度的视场角，在250mm成像距离下有120倍的放大倍数，具有超薄特性；4采用大相对孔径设计，相对孔径为2.0～2.4，提高像平面上的光照度；5采用像方远心成像方法，保证像面辐照度均匀。

The relation between the accumulative ultraviolet irradiation time and the chromatic aberration of 2-D color barcodes is analyzed based on the CIELAB model. The detection results of four-color printed label show that the fading velocity of fuchsine is faster than cyan, yellow and black.

基于CIELAB模型分析紫外辐照累计时间与二维条形码色差的关系，对4色打印标签的检测结果表明：品红色褪变速率较大，青色、黄色和黑色的褪变速率逐次减小。
