Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx =>B"j`oR  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm oI[

rxr  
Type: Double Bounces ,ofE*Wt  
The '****' denotes a possible internal focus ZJQFn  
RMS is the RMS spot radius on axis at the primary wavelength. 16Jq*hKU  
RMS values of 0.00 indicate that an accurate RMS Hz."4nhv  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is &Cv  
non-rotationally symmetric or uses non-standard surfaces.
