Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx Opg#*w%-  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm }uO5q42  
Type: Double Bounces je%M AgW`  
The '****' denotes a possible internal focus u=K2Q4  
RMS is the RMS spot radius on axis at the primary wavelength. `iixq9xi  
RMS values of 0.00 indicate that an accurate RMS :b#%C pR  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is pWaPC/,g  
non-rotationally symmetric or uses non-standard surfaces.
