Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 1W*V2`0>  
Type: Double Bounces IZ+*`E  
The '****' denotes a possible internal focus D=2~37CzQ1  
RMS is the RMS spot radius on axis at the primary wavelength. !{$qMhT  
RMS values of 0.00 indicate that an accurate RMS 5RW@_%C  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is Dp^"J85}   
non-rotationally symmetric or uses non-standard surfaces.
