Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm %H 8A=  
Type: Double Bounces ev)rOcOU  
The '****' denotes a possible internal focus ]u\
`  
RMS is the RMS spot radius on axis at the primary wavelength. :5$xh  
RMS values of 0.00 indicate that an accurate RMS MT;SRAmUr  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is gcQ.  YP9  
non-rotationally symmetric or uses non-standard surfaces.
