Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx j$@tK0P  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm <n0{7#PDqw  
Type: Double Bounces f} K`Jm_}?  
The '****' denotes a possible internal focus \C|cp|A*&  
RMS is the RMS spot radius on axis at the primary wavelength. ,E*R,'w   
RMS values of 0.00 indicate that an accurate RMS mN}7H:,  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is Wd 2sh  
non-rotationally symmetric or uses non-standard surfaces.
