Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx #3VOC#.  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm -9PJ4"H  
Type: Double Bounces QK~44;LVIJ  
The '****' denotes a possible internal focus ,gO}H)v]t  
RMS is the RMS spot radius on axis at the primary wavelength. Zc!rL0
T  
RMS values of 0.00 indicate that an accurate RMS PI G3kJ  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ,5*Z<[*  
non-rotationally symmetric or uses non-standard surfaces.
