Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 7'-j%!#w  
Type: Double Bounces +~ #U7xgq/  
The '****' denotes a possible internal focus cf7v[ZZ}  
RMS is the RMS spot radius on axis at the primary wavelength. fof2 xcH!  
RMS values of 0.00 indicate that an accurate RMS \i[BP  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 0iZGPe~  
non-rotationally symmetric or uses non-standard surfaces.
