Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm j8#B  
Type: Double Bounces @awN*mO  
The '****' denotes a possible internal focus `(?x@Y>.Ht  
RMS is the RMS spot radius on axis at the primary wavelength. [P"R+$"   
RMS values of 0.00 indicate that an accurate RMS |p{FSS  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is bLi>jE.%.  
non-rotationally symmetric or uses non-standard surfaces.
