Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm F)~>4>hPr  
Type: Double Bounces ;-"!
p  
The '****' denotes a possible internal focus ,ASNa^7/>  
RMS is the RMS spot radius on axis at the primary wavelength. ~8&->?{  
RMS values of 0.00 indicate that an accurate RMS odca?  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is tW~kn9glZ  
non-rotationally symmetric or uses non-standard surfaces.
