Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 4TUe*F@ ML  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm ;<MHDmD  
Type: Double Bounces #2|sS|0<  
The '****' denotes a possible internal focus X2Y-TET  
RMS is the RMS spot radius on axis at the primary wavelength. N(/DC)DJg  
RMS values of 0.00 indicate that an accurate RMS SC"=M^E  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is \Ui8Sgeei  
non-rotationally symmetric or uses non-standard surfaces.
