Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx ~6HDW  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm JJ-i_5\q  
Type: Double Bounces ox4W$YdMG  
The '****' denotes a possible internal focus }NwN2xTB  
RMS is the RMS spot radius on axis at the primary wavelength. Z Xb}R^O-  
RMS values of 0.00 indicate that an accurate RMS h[Mdr  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is s.rT]  
non-rotationally symmetric or uses non-standard surfaces.
