Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx ef2)k4)"  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm N1hj[G[H"  
Type: Double Bounces W0<2*7s  
The '****' denotes a possible internal focus +*wr=9>  
RMS is the RMS spot radius on axis at the primary wavelength. Ho1V)T
>  
RMS values of 0.00 indicate that an accurate RMS 9ePom'1f1  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is -PTfsQk  
non-rotationally symmetric or uses non-standard surfaces.
