Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 4%I(Z'*Cx  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm Tx7YHE6{  
Type: Double Bounces .baS mfc  
The '****' denotes a possible internal focus GBZx@B[TY  
RMS is the RMS spot radius on axis at the primary wavelength. q#RVi8('  
RMS values of 0.00 indicate that an accurate RMS {-]/r  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is \8!&XcA  
non-rotationally symmetric or uses non-standard surfaces.
