Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx K#>B'>A\  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm d2pVO]l YZ  
Type: Double Bounces .mMM]*e[0  
The '****' denotes a possible internal focus L!\I>a5C0G  
RMS is the RMS spot radius on axis at the primary wavelength. 8{AzB8xp  
RMS values of 0.00 indicate that an accurate RMS ).\%a h  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is =cxjb,r  
non-rotationally symmetric or uses non-standard surfaces.
