Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx cm8co  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm hltUf5m'b  
Type: Double Bounces 8lyNg w1  
The '****' denotes a possible internal focus ^?: Az  
RMS is the RMS spot radius on axis at the primary wavelength. .]0:`Y,;  
RMS values of 0.00 indicate that an accurate RMS Uw?25+[b  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is _PLZ_c:O  
non-rotationally symmetric or uses non-standard surfaces.
