Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx d6JW"  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm zF>;7'\x  
Type: Double Bounces w3sU&  |N  
The '****' denotes a possible internal focus zn&ZXFgN  
RMS is the RMS spot radius on axis at the primary wavelength. q
165S  
RMS values of 0.00 indicate that an accurate RMS xLi3|^q  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 5p:BHw;%;  
non-rotationally symmetric or uses non-standard surfaces.
