Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 4WXr~?Vq9  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm IylfMwLC  
Type: Double Bounces OfPv'rW{x  
The '****' denotes a possible internal focus yF@72tK  
RMS is the RMS spot radius on axis at the primary wavelength. @B9O*x+n:  
RMS values of 0.00 indicate that an accurate RMS b NR@d'U  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ~9Cw5rwH<;  
non-rotationally symmetric or uses non-standard surfaces.
