查询词典 chromatic aberration

If there is a value of chromatic aberration in each group, and a certain relationship between the positive or negative sign of chromatic aberration and the selection of glasses, the secondary spectrum of the whole lens system can be reduced to any small value.

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。

Answer: On-line shopping chromatic aberration is avoidless,each picture we can proofread the color according to the material object,but in the different environment light, under the monitor will have the chromatic aberration question,please completely do not accept any chromatic aberration the buyer to consider after clear, will purchase.

答：网上购物色差是无法避免的，每张照片我们都会根据实物校对过颜色，但在不同的环境灯光，显示器下都会有色差问题，请完全不能接受任何色差的买家考虑清楚后购买。

Network sells the avoidless chromatic aberration: Each picture I will have proofread the color according to the material object, but under the different color\'s light, under the different monitor looked that the commodity can create the chromatic aberration problem, therefore please completely do not accept any chromatic aberration MM to look by all means must the clear this provision, and considered clear will purchase again.

网络销售无法避免色差：每张照片我都会根据实物校对过颜色，但在不同颜色的灯光下、在不同的显示器下看商品都会造成色差问题，所以请完全不能接受任何色差的MM务必看清楚此条款，并考虑清楚再购买。

Because the seller does not undertake the buyer to choose the loss which wrongly the size produces.the ● network sells the avoidless chromatic aberration: Each picture I will have proofread the color according to the material object, but under the different color\'s light, under the different monitor looked that the commodity can create the chromatic aberration problem, therefore please completely do not accept any chromatic aberration MM to look by all means must the clear this provision, and considered clear will purchase again.

卖家不承担买家因错误选择尺寸而产生的损失。●网络销售无法避免色差：每张照片我都会根据实物校对过颜色，但在不同颜色的灯光下、在不同的显示器下看商品都会造成色差问题，所以请完全不能接受任何色差的MM务必看清楚此条款，并考虑清楚再购买。

The chromatic aberration was decreased for filler adding, and the decrease was the biggest by CaCO3, the smallest decrease is TiO2. The chromatic aberration decreased gradually with CaCO3 dosage, however, the chromatic aberration changed little when CaCO3 dosage is greater than 20%; also the two-sidedness of paper was improved by filling.

填料的使用明显降低了色差值，其中降低最显著的为碳酸钙，最少的二氧化钛，碳酸钙用量的增大导致色差值逐渐降低，当碳酸钙用量大于20%后，色差值变化很小，但加填改善了色差值两面差的问题。
