Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm Bm65W  
Type: Double Bounces )PsN_ 42~  
The '****' denotes a possible internal focus `4$4bXrP'  
RMS is the RMS spot radius on axis at the primary wavelength. 2Px$0&VN  
RMS values of 0.00 indicate that an accurate RMS y|FBYcn#F  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is k'6<jEbk  
non-rotationally symmetric or uses non-standard surfaces.
