Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx Z&Y=`GOI  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm TX}T|ri  
Type: Double Bounces *)<B0SjT  
The '****' denotes a possible internal focus \8S~c8Z~  
RMS is the RMS spot radius on axis at the primary wavelength. f$.?$  
RMS values of 0.00 indicate that an accurate RMS ZE?f!ifp  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is gn8|/ev  
non-rotationally symmetric or uses non-standard surfaces.
