Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx ~qP_1() ?  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm {Z^ G]@  
Type: Double Bounces C~:@ETcbil  
The '****' denotes a possible internal focus gvLzE&V}  
RMS is the RMS spot radius on axis at the primary wavelength. xG|T_|?  
RMS values of 0.00 indicate that an accurate RMS Nt5`F@;B  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is OqcM3#  
non-rotationally symmetric or uses non-standard surfaces.
