Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx ^5'pJ/BV  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm !k3 eUBF  
Type: Double Bounces s7d4)A%  
The '****' denotes a possible internal focus H^3f!\MC;o  
RMS is the RMS spot radius on axis at the primary wavelength. #zf,%IYF  
RMS values of 0.00 indicate that an accurate RMS Q6 oM$qiM  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ohJo1}{  
non-rotationally symmetric or uses non-standard surfaces.
