Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm @cSz!E}  
Type: Double Bounces V,{ydxfB  
The '****' denotes a possible internal focus QH#|R92:  
RMS is the RMS spot radius on axis at the primary wavelength. jC<<S  
RMS values of 0.00 indicate that an accurate RMS [u/g =^+u  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is &LHQ)?
