Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx "kMzmo=Pv5  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm Lju7,/UD  
Type: Double Bounces Cz#Z<:  
The '****' denotes a possible internal focus fr6^
nDY  
RMS is the RMS spot radius on axis at the primary wavelength. ;d.K_P  
RMS values of 0.00 indicate that an accurate RMS !X>=l  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is q*jNH\|  
non-rotationally symmetric or uses non-standard surfaces.
