Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx "x"y3v'  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm KD*q|?Z  
Type: Double Bounces UomO^P  
The '****' denotes a possible internal focus gT=RJB  
RMS is the RMS spot radius on axis at the primary wavelength. L>PPAI  
RMS values of 0.00 indicate that an accurate RMS uA1DTr?z  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is K]0K/~>8  
non-rotationally symmetric or uses non-standard surfaces.
