Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm D1 z3E;:  
Type: Double Bounces {D8IA3w  
The '****' denotes a possible internal focus QB>e(j%  
RMS is the RMS spot radius on axis at the primary wavelength. j>zVC;Sj*  
RMS values of 0.00 indicate that an accurate RMS '@bA_F(  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 2{\Y<%.
