Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx T[=XGAJ  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm DU7kZ  
Type: Double Bounces J,fXXi)J  
The '****' denotes a possible internal focus oy'Q#!  
RMS is the RMS spot radius on axis at the primary wavelength. E0c5c  
RMS values of 0.00 indicate that an accurate RMS [Bp[=\  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is %HuQc^  
non-rotationally symmetric or uses non-standard surfaces.
