Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx $=QGua V  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 3{#pd6e5  
Type: Double Bounces g#KToOP  
The '****' denotes a possible internal focus 2Ws/0c  
RMS is the RMS spot radius on axis at the primary wavelength. v BeU  
RMS values of 0.00 indicate that an accurate RMS S
1^Mw;?P  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is |uBot#K|  
non-rotationally symmetric or uses non-standard surfaces.
