Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx /7a3*a  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm vZ6R>f  
Type: Double Bounces uzp\<\d-t  
The '****' denotes a possible internal focus TL-ALtG  
RMS is the RMS spot radius on axis at the primary wavelength. f*m^x7  
RMS values of 0.00 indicate that an accurate RMS 5yW}#W>  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is gId :IR  
non-rotationally symmetric or uses non-standard surfaces.
