Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx M=lU`Sm  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm yj#*H  
Type: Double Bounces GZ,MC?W  
The '****' denotes a possible internal focus 8?Ju\W  
RMS is the RMS spot radius on axis at the primary wavelength. 4dcm)Xr  
RMS values of 0.00 indicate that an accurate RMS 3T0~k--  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 'Grii,  
non-rotationally symmetric or uses non-standard surfaces.
