Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx {Z!x]}{M  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm Ww)p&don  
Type: Double Bounces :Y)jf
 
The '****' denotes a possible internal focus 8DLj?M>N  
RMS is the RMS spot radius on axis at the primary wavelength. RF$2p4=[  
RMS values of 0.00 indicate that an accurate RMS vA"MTncv  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is +p"}F PIK  
non-rotationally symmetric or uses non-standard surfaces.
