Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx -I#1xJU  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm S+EC!;@Xg  
Type: Double Bounces J 4EG  
The '****' denotes a possible internal focus RwC1C(ZP  
RMS is the RMS spot radius on axis at the primary wavelength. b:uMON,H  
RMS values of 0.00 indicate that an accurate RMS &jHnM^nQ  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is .oFkx*Ln  
non-rotationally symmetric or uses non-standard surfaces.
