Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx VN<baK%]  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 2rX}A3%9^^  
Type: Double Bounces 3_c4+u"6  
The '****' denotes a possible internal focus {Gr"oO`&"  
RMS is the RMS spot radius on axis at the primary wavelength. *|/kK
vN  
RMS values of 0.00 indicate that an accurate RMS v!rOT/I  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is z_9qT"vF  
non-rotationally symmetric or uses non-standard surfaces.
