Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx $7i[7S4  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm VRD^>Gi  
Type: Double Bounces y%kZ##  
The '****' denotes a possible internal focus Vry_X2  
RMS is the RMS spot radius on axis at the primary wavelength. X:g#&e_  
RMS values of 0.00 indicate that an accurate RMS zZ<
*  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is (hQi {  
non-rotationally symmetric or uses non-standard surfaces.
