Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx gJ7puN  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm }y/t~f+  
Type: Double Bounces *?'T8yf^  
The '****' denotes a possible internal focus \H(,'w7H  
RMS is the RMS spot radius on axis at the primary wavelength. ~h.B\Sc]Q  
RMS values of 0.00 indicate that an accurate RMS 5+Ut]AL5  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is S22;g  
non-rotationally symmetric or uses non-standard surfaces.
