Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx hUuKkUR+Ir  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm xR|^{y9n  
Type: Double Bounces c!'\k,ma<9  
The '****' denotes a possible internal focus k7;i^$@c  
RMS is the RMS spot radius on axis at the primary wavelength. {?2|rv)  
RMS values of 0.00 indicate that an accurate RMS I|qhj*_C  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is DdUw~n,  
non-rotationally symmetric or uses non-standard surfaces.
