Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx cQh=Mri]  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm T7Yg^ -"  
Type: Double Bounces 42 Sk`  
The '****' denotes a possible internal focus e3kdIOu5  
RMS is the RMS spot radius on axis at the primary wavelength. w4Ku1G#jC  
RMS values of 0.00 indicate that an accurate RMS G[!<mh4h|  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is AI2>{V  
non-rotationally symmetric or uses non-standard surfaces.
