Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx .@r{Tq,%q8  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm =|O]X|y-lZ  
Type: Double Bounces ~K)FuL[*  
The '****' denotes a possible internal focus 6_8yQ  
RMS is the RMS spot radius on axis at the primary wavelength. wBI:}N@.  
RMS values of 0.00 indicate that an accurate RMS $0{h Uex  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is p? +!*BZ  
non-rotationally symmetric or uses non-standard surfaces.
