Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 4 Y9`IgQ  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm |`,2ri*5A  
Type: Double Bounces IH&|Tcf\  
The '****' denotes a possible internal focus 6NuD4Ga  
RMS is the RMS spot radius on axis at the primary wavelength. \0I_<  
RMS values of 0.00 indicate that an accurate RMS Y>T-af49  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is Apag{Z]^B  
non-rotationally symmetric or uses non-standard surfaces.
