Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx IO:G1;[/2L  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm -`6+UkOV[x  
Type: Double Bounces Y`wSv NU  
The '****' denotes a possible internal focus .6 ?U@2  
RMS is the RMS spot radius on axis at the primary wavelength. Ilm^G}GB  
RMS values of 0.00 indicate that an accurate RMS UJ6v(:z<  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is C+&l< fM&  
non-rotationally symmetric or uses non-standard surfaces.
