Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm <GF)5QB  
Type: Double Bounces N6c']!aM@  
The '****' denotes a possible internal focus
W8,XSUl  
RMS is the RMS spot radius on axis at the primary wavelength. g.kpUs  
RMS values of 0.00 indicate that an accurate RMS 5@tpJ8E8$  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is u6'vzLmM  
non-rotationally symmetric or uses non-standard surfaces.
