Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx [! o-F;  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm YLr2j 7  
Type: Double Bounces Z/;SR""wa  
The '****' denotes a possible internal focus Mqy`j9FbL  
RMS is the RMS spot radius on axis at the primary wavelength. :H7 "W<  
RMS values of 0.00 indicate that an accurate RMS Sy~Mh]{E  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is =ye}IpC*M  
non-rotationally symmetric or uses non-standard surfaces.
