Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx b8_F2  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm yVgC1-8i*  
Type: Double Bounces fZj,Q#}D  
The '****' denotes a possible internal focus yIcTc  
RMS is the RMS spot radius on axis at the primary wavelength. =7JSJ98  
RMS values of 0.00 indicate that an accurate RMS q
-+:1E  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is F}7sb#G  
non-rotationally symmetric or uses non-standard surfaces.
