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. @va6,^)

Fields: Generally speaking, the field definitions used for optimization and analysis are inadequate for D}Z].c@E
tolerancing. for example, a rotationally symmetric lens may use field definitions of 0, 7, and 10 degrees. For klv ]+F&[
tolerancing purposes, the lack of symmetry in the field definitions may cause inaccurate results when analyzing ]QRhTz
tilt or decenter tolerances. When constructing a merit function to use for tolerancing ZEMAX can use three LC2t,!RRl&
different field settings: cW%F%:b
Y-Symmetric: ZEMAX computes the maximum field coordinate, then defines new field points at +1.0, +0.7, MYDAS-
0.0, -0.7, and -1.0 times the maximum field coordinate, in the Y direction only. All X field values are set to uee2WGD
zero. This is the default for rotationally symmetric lenses. }"E?#&^
XY-Symmetric: Similar to Y-Symmetric, except there are 9 field points used. The 5 Y-Symmetric points are )Yy`$`
used, and -1.0, -0.7, +0.7, and +1.0 are added in the X axis direction only. }qRYXjS
User Defined: Use whatever field definitions exist in the current lens file. This option is required when using fU8 &fo%ER
vignetting factors, tolerancing multiple configuration lenses, or using tolerance scripts. It is also highly 7jvf:#\LtL
recommended when tolerancing non rotationally symmetric lenses or lenses with complex field weighting ,aU_bve
that user defined fields be used.
