Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx  3kAmRU  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm >d.o1<  
Type: Double Bounces G#V}9l
8Q  
The '****' denotes a possible internal focus Kd2?9gaw  
RMS is the RMS spot radius on axis at the primary wavelength. ")J\} $r  
RMS values of 0.00 indicate that an accurate RMS RYU(z;+0p  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is h8IjTd]z{$  
non-rotationally symmetric or uses non-standard surfaces.
