Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx i $;y  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm j<C p&}X  
Type: Double Bounces [pYjH+<  
The '****' denotes a possible internal focus Swnom?t  
RMS is the RMS spot radius on axis at the primary wavelength. 7)37AKw  
RMS values of 0.00 indicate that an accurate RMS g RBbL1  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is zTS#o#`!\  
non-rotationally symmetric or uses non-standard surfaces.
