Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm ^Jkj/n'  
Type: Double Bounces 9xu&n%L=  
The '****' denotes a possible internal focus E+3~w?1  
RMS is the RMS spot radius on axis at the primary wavelength. GZ4{<QG  
RMS values of 0.00 indicate that an accurate RMS )s^XVs.-  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is >#8`Zy:/Y  
non-rotationally symmetric or uses non-standard surfaces.
