2.
The equation of the corrector plate which was based on the third-order aberration theory was approved for a long time.
施密特系统历史悠久,过去从三级象差理论得到的校正板方程式,也一直被人们所认同,但是此方程经光学设计软件验证后,发现α≠1/2r_(02),其中r_(02)为校正板的顶点曲率半径,∑S_1≠0,系统的焦距和后截距也有一定的偏差,与三级像差理论不符。
3.
Based on the third-order aberration theory the initial configuration parameters of the mirror compensator in testing the conicoid are solved in theory,making spherical aberration coefficient ∑S_1=0,and the relations between the compensating mirror and the tested mirror are given,with the surface of compensator chosen as sphere or ellipsoid.
通过三级像差理论求解反射镜补偿检验二次曲面的初始结构参量,令球差系数∑S1=0,补偿镜e21可选择球面或椭球面,推导出补偿镜和待检镜之间关系的表示式e。
补充资料:彗形像差
分子式:
CAS号:

性质: 简称彗差。像差的一种。由偏离凸透镜光轴的发光物点所发出的宽带单色光,穿过透镜以后,在焦面上所得到的像是不清晰的,它扩展成彗星形状的亮斑,故称彗差。适当选择透镜的两个曲率半径或在透镜前加一个中间光阑,可减小或消除彗差。
