zmH8^:-x  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm _&V%idz!0  
Type: Double Bounces Ne<={u%  
The '****' denotes a possible internal focus j5Kw0Wy7  
RMS is the RMS spot radius on axis at the primary wavelength. G&,1 NjSi  
RMS values of 0.00 indicate that an accurate RMS |osu4=s|  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is wpgO09  
non-rotationally symmetric or uses non-standard surfaces.
