Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm fbHW
Bb  
Type: Double Bounces zO).<xIq+  
The '****' denotes a possible internal focus J/]o WC`u  
RMS is the RMS spot radius on axis at the primary wavelength. iJdrY6qd  
RMS values of 0.00 indicate that an accurate RMS y,y/Py
N)  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is C>JekPeM  
non-rotationally symmetric or uses non-standard surfaces.
