垂轴色差

在成像光学系统的设计过程中必须对其垂轴色差进行校正。

The lateral chromatic aberration must be corrected during designing optical system .

对于目镜中需要重点校正的像散和垂轴色差的最大值分别为0.58mm和18μm，而最大畸变也仅为3.3%；

For the image quality , the astigmatic and lateral color of the key aberrations of eyepiece are 0.58 mm and 18 μ m , and the distortion is only 3.3 % .

垂轴色差降低了1个数量级，像散降低了34%，垂轴像差对于0°、49°和70°视场分别降低了30%、16%和20%；

The lateral color reduces by one order in magnitude , the astigmatism reduces by 34 % , and the transverse aberration reduces by 30 % , 16 % and 20 % for 0 °, 49 ° and 70 ° field of views .

该系统垂轴色差小于42μm，视场扩大为40°（水平）×30°（垂直），分辨力接近人眼的最小分辨能力；

The vertical axis chromatic aberration of the system is less than 42 μ m in visible light band and its field of view enlarges to 40 ° ( horizontal )× 30 °( vertical ) . Its resolution has approached the minimal resolving capability of human eye .
