Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm D6dliU?k  
Type: Double Bounces M}! qH.W  
The '****' denotes a possible internal focus zv7)JH7EV&  
RMS is the RMS spot radius on axis at the primary wavelength. y>#_LhTX-  
RMS values of 0.00 indicate that an accurate RMS \.aKxj5
  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is {?;qy\m]o  
non-rotationally symmetric or uses non-standard surfaces.
