Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx *Tq7[v{0*|  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm PUC:Pl77  
Type: Double Bounces F 7X] h  
The '****' denotes a possible internal focus 7lAnGP.;  
RMS is the RMS spot radius on axis at the primary wavelength. alyA#zao|  
RMS values of 0.00 indicate that an accurate RMS h4c4!S  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 5G=fJAG  
non-rotationally symmetric or uses non-standard surfaces.
