Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx /VRUz++K  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm CfQf7-  
Type: Double Bounces  qovQ9O  
The '****' denotes a possible internal focus &(gm4bTg  
RMS is the RMS spot radius on axis at the primary wavelength. riID,aut  
RMS values of 0.00 indicate that an accurate RMS 0;}Aj8Fle  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is pPoH5CzcK  
non-rotationally symmetric or uses non-standard surfaces.
