Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx ]c67zyX=%  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm K *<+K<Tp  
Type: Double Bounces x#_\b-  
The '****' denotes a possible internal focus XZ|%9#6  
RMS is the RMS spot radius on axis at the primary wavelength. 4pYscB  
RMS values of 0.00 indicate that an accurate RMS .(RX;.lw  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 5:oteNc

non-rotationally symmetric or uses non-standard surfaces.
