Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx `_{'qqRhe  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm AHsp:0Ma#  
Type: Double Bounces G=4Da~<ij  
The '****' denotes a possible internal focus Zw(*q?9\  
RMS is the RMS spot radius on axis at the primary wavelength. j^A0[:2  
RMS values of 0.00 indicate that an accurate RMS Bv
x%|:R  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 1M&n=s _  
non-rotationally symmetric or uses non-standard surfaces.
