Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm GL<u#[  
Type: Double Bounces zXRq) ;s  
The '****' denotes a possible internal focus CW)JS3}W"  
RMS is the RMS spot radius on axis at the primary wavelength. ~?#B(t  
RMS values of 0.00 indicate that an accurate RMS #lld*I"d  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is <*'%Xgm  
non-rotationally symmetric or uses non-standard surfaces.
