Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx Cu&y',ee~  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm AMf{E  
Type: Double Bounces e-Ma8+X\  
The '****' denotes a possible internal focus f'?FYBL  
RMS is the RMS spot radius on axis at the primary wavelength. ]
CxDm  
RMS values of 0.00 indicate that an accurate RMS o4F(X0  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is `b?o%5V2x  
non-rotationally symmetric or uses non-standard surfaces.
