Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx vmU@^2JSJ  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm "i nd$Z`c  
Type: Double Bounces 5&QJ7B,!  
The '****' denotes a possible internal focus B-xGX$<z  
RMS is the RMS spot radius on axis at the primary wavelength. y^;#&k!
 
RMS values of 0.00 indicate that an accurate RMS '9laa=H%8  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 2y//

non-rotationally symmetric or uses non-standard surfaces.
