Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx !O#dV1wAa  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 3Te^  
Type: Double Bounces y /BJIQ  
The '****' denotes a possible internal focus 5i-Rglo  
RMS is the RMS spot radius on axis at the primary wavelength. 2OwV^-OG  
RMS values of 0.00 indicate that an accurate RMS ~>:Z6Le@  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is IR-dU<<9O  
non-rotationally symmetric or uses non-standard surfaces.
