Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx S5]rIcM  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm .Rxz;-VA  
Type: Double Bounces l=%v  
The '****' denotes a possible internal focus ipfiarT~)  
RMS is the RMS spot radius on axis at the primary wavelength. 'bj$ZM9  
RMS values of 0.00 indicate that an accurate RMS hH8:7i  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is -8&M^-  
non-rotationally symmetric or uses non-standard surfaces.
