Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx dZFf/BXU  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 8~YhT]R=  
Type: Double Bounces gXZC%S  
The '****' denotes a possible internal focus |Gx-c ,{{  
RMS is the RMS spot radius on axis at the primary wavelength. 4:.yE|@h[  
RMS values of 0.00 indicate that an accurate RMS T?4MFx#  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is OBqaf )W  
non-rotationally symmetric or uses non-standard surfaces.
