Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx g}HB|$P7  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm r~ gjn`W  
Type: Double Bounces W'2T7ha Es  
The '****' denotes a possible internal focus H}G=%j0  
RMS is the RMS spot radius on axis at the primary wavelength. i oCoFj  
RMS values of 0.00 indicate that an accurate RMS V mxVE=l  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is *=UxX ]0y  
non-rotationally symmetric or uses non-standard surfaces.
