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. w/ (c}%v}=

Fields: Generally speaking, the field definitions used for optimization and analysis are inadequate for ( tOhuSW
tolerancing. for example, a rotationally symmetric lens may use field definitions of 0, 7, and 10 degrees. For 1}c'UEr%)
tolerancing purposes, the lack of symmetry in the field definitions may cause inaccurate results when analyzing ^/#G,MxNy
tilt or decenter tolerances. When constructing a merit function to use for tolerancing ZEMAX can use three 83SK<V6
different field settings: ~/9RSdv7
Y-Symmetric: ZEMAX computes the maximum field coordinate, then defines new field points at +1.0, +0.7, e\ cyi W0
0.0, -0.7, and -1.0 times the maximum field coordinate, in the Y direction only. All X field values are set to oKCy,Ot<
zero. This is the default for rotationally symmetric lenses. r A(A$VR
XY-Symmetric: Similar to Y-Symmetric, except there are 9 field points used. The 5 Y-Symmetric points are ]W14'Z
used, and -1.0, -0.7, +0.7, and +1.0 are added in the X axis direction only. N`,\1hHMT
User Defined: Use whatever field definitions exist in the current lens file. This option is required when using `G/g/>y
vignetting factors, tolerancing multiple configuration lenses, or using tolerance scripts. It is also highly

recommended when tolerancing non rotationally symmetric lenses or lenses with complex field weighting )J> dGIb
that user defined fields be used.
