Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx kNEEu!G  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm b'H'QY   
Type: Double Bounces -Mt
5< s  
The '****' denotes a possible internal focus RgE`Hr  
RMS is the RMS spot radius on axis at the primary wavelength. Y::0v@&(  
RMS values of 0.00 indicate that an accurate RMS U=on}W3V2  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is aER|5!7(2\  
non-rotationally symmetric or uses non-standard surfaces.
