Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx BYDOTy/%nJ  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm ]\R%@FCYc  
Type: Double Bounces d7QWK(d  
The '****' denotes a possible internal focus V,9UOC,Gn  
RMS is the RMS spot radius on axis at the primary wavelength. @6DV?VL  
RMS values of 0.00 indicate that an accurate RMS _
{gRCR)  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is !U+XIr  
non-rotationally symmetric or uses non-standard surfaces.
