Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx DfU= i'R  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm _(~LXk
^C  
Type: Double Bounces GVu[X?q@|  
The '****' denotes a possible internal focus c`hENPhW  
RMS is the RMS spot radius on axis at the primary wavelength. ^c/3!"wK  
RMS values of 0.00 indicate that an accurate RMS v _:KqdmO]  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ;&f(7 Q+T_  
non-rotationally symmetric or uses non-standard surfaces.
