還有一點忘了說了, 就是公差計算時的視場設(shè)定? 是Y對稱? XY對稱? 用戶自定義? 我的解釋只是針對用戶自定義時的結(jié)果. [)k2=67

Fields: Generally speaking, the field definitions used for optimization and analysis are inadequate for #8E?^d
tolerancing. for example, a rotationally symmetric lens may use field definitions of 0, 7, and 10 degrees. For ^@N`e1
tolerancing purposes, the lack of symmetry in the field definitions may cause inaccurate results when analyzing lR[z<2w\
tilt or decenter tolerances. When constructing a merit function to use for tolerancing ZEMAX can use three ]]3Q*bq4
different field settings: ?M]u$Te/.
Y-Symmetric: ZEMAX computes the maximum field coordinate, then defines new field points at +1.0, +0.7, D0KELAcY
0.0, -0.7, and -1.0 times the maximum field coordinate, in the Y direction only. All X field values are set to bx]14}6
zero. This is the default for rotationally symmetric lenses. a^x

XY-Symmetric: Similar to Y-Symmetric, except there are 9 field points used. The 5 Y-Symmetric points are 1V\1]J/
used, and -1.0, -0.7, +0.7, and +1.0 are added in the X axis direction only. +ruj
User Defined: Use whatever field definitions exist in the current lens file. This option is required when using 4zwif&
vignetting factors, tolerancing multiple configuration lenses, or using tolerance scripts. It is also highly ZgK@Fl*k
recommended when tolerancing non rotationally symmetric lenses or lenses with complex field weighting >!<V\
