Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx O-|3k$'\z  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm oNdO@i%.q4  
Type: Double Bounces ' ZB%McS  
The '****' denotes a possible internal focus nQgn^z#  
RMS is the RMS spot radius on axis at the primary wavelength. 1|%$ie  
RMS values of 0.00 indicate that an accurate RMS qzG'Gz{{qu  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ]F_u  
non-rotationally symmetric or uses non-standard surfaces.
