Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm Q.8)_w  
Type: Double Bounces jr9/  
The '****' denotes a possible internal focus X@[)jWs  
RMS is the RMS spot radius on axis at the primary wavelength. rkW2_UTZE  
RMS values of 0.00 indicate that an accurate RMS qPc"A!-i  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is D=Pv:)*]  
non-rotationally symmetric or uses non-standard surfaces.
