Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx _uYidtxo=  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm qM$4c7'4P6  
Type: Double Bounces uuD|%-Ng  
The '****' denotes a possible internal focus m=qEQy6#2u  
RMS is the RMS spot radius on axis at the primary wavelength. <r@w`G  
RMS values of 0.00 indicate that an accurate RMS d7f{2  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is QGR}`n2D  
non-rotationally symmetric or uses non-standard surfaces.
