还有一点忘了说了, 就是公差计算时的视场设定? 是Y对称? XY对称? 用户自定义? 我的解释只是针对用户自定义时的结果. n93zD*;5

Fields: Generally speaking, the field definitions used for optimization and analysis are inadequate for uA\J0"0; }
tolerancing. for example, a rotationally symmetric lens may use field definitions of 0, 7, and 10 degrees. For

tilt or decenter tolerances. When constructing a merit function to use for tolerancing ZEMAX can use three #J$qa Ul
different field settings: \+Y!ILOI
Y-Symmetric: ZEMAX computes the maximum field coordinate, then defines new field points at +1.0, +0.7, l2&hBacT
0.0, -0.7, and -1.0 times the maximum field coordinate, in the Y direction only. All X field values are set to rAXX}"l6s
zero. This is the default for rotationally symmetric lenses. ^\wl2
XY-Symmetric: Similar to Y-Symmetric, except there are 9 field points used. The 5 Y-Symmetric points are 0YS?=oi
used, and -1.0, -0.7, +0.7, and +1.0 are added in the X axis direction only. &U &%ka<*
User Defined: Use whatever field definitions exist in the current lens file. This option is required when using >. LKct*5K
vignetting factors, tolerancing multiple configuration lenses, or using tolerance scripts. It is also highly j>'B [

that user defined fields be used.
