Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx \=Od1i  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm FmgMd)#  
Type: Double Bounces WAJKP"  
The '****' denotes a possible internal focus jtgj h\Nt  
RMS is the RMS spot radius on axis at the primary wavelength. 0 gR_1~3  
RMS values of 0.00 indicate that an accurate RMS S2>$S^[U  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is MhIHfW]b  
non-rotationally symmetric or uses non-standard surfaces.
