Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx vxZUtyJfe  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm @TG~fJSA12  
Type: Double Bounces <VsZ$  
The '****' denotes a possible internal focus ^?`,f>`M  
RMS is the RMS spot radius on axis at the primary wavelength. 'v)+S;oB  
RMS values of 0.00 indicate that an accurate RMS pDN,(Ip  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 1#RA+d(  
non-rotationally symmetric or uses non-standard surfaces.
