Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm s~ou$!|  
Type: Double Bounces v3G$9(NE;  
The '****' denotes a possible internal focus rs,'vV-2\  
RMS is the RMS spot radius on axis at the primary wavelength. ,N nh$F  
RMS values of 0.00 indicate that an accurate RMS 4_# (y^9  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is QP<.~^ao  
non-rotationally symmetric or uses non-standard surfaces.
