Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx kud2O>>  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm u9%AK g}~  
Type: Double Bounces d$v{oC}  
The '****' denotes a possible internal focus ;V)94YT  
RMS is the RMS spot radius on axis at the primary wavelength. BaE}|4  
RMS values of 0.00 indicate that an accurate RMS =N{-lyr)  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is K${CHKFf  
non-rotationally symmetric or uses non-standard surfaces.
