Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm AH|'{  
Type: Double Bounces g-<[* nF  
The '****' denotes a possible internal focus sfR0wEqI  
RMS is the RMS spot radius on axis at the primary wavelength. ;aImz*1%t  
RMS values of 0.00 indicate that an accurate RMS u"-."_  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 9d8U
