Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx Jw86P=  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 'Oq}BVR&  
Type: Double Bounces 4BCZ~_  
The '****' denotes a possible internal focus k1%Ek#5  
RMS is the RMS spot radius on axis at the primary wavelength. ZLO_5#<  
RMS values of 0.00 indicate that an accurate RMS Xe%n.DW m  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is %i^%D  
non-rotationally symmetric or uses non-standard surfaces.
