Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx @x;(yqOb  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 7Jz9%iP  
Type: Double Bounces 77wod}h!:  
The '****' denotes a possible internal focus :)kHXOb.  
RMS is the RMS spot radius on axis at the primary wavelength. 8:0,jnS  
RMS values of 0.00 indicate that an accurate RMS QjYw^[o  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is |$+/IxDP  
non-rotationally symmetric or uses non-standard surfaces.
