Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx s"|N-A=cS  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm HiG&`:P>q  
Type: Double Bounces P( W8XC  
The '****' denotes a possible internal focus G#! j`  
RMS is the RMS spot radius on axis at the primary wavelength. `
v)-v<  
RMS values of 0.00 indicate that an accurate RMS E 2DTE  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is -3r&O:  
non-rotationally symmetric or uses non-standard surfaces.
