Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm z"7I5N  
Type: Double Bounces }~B@Z\`O  
The '****' denotes a possible internal focus jhRg47A  
RMS is the RMS spot radius on axis at the primary wavelength. M1nH!A~o  
RMS values of 0.00 indicate that an accurate RMS V2Iqk]V%y  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ~!V5Ug_2  
non-rotationally symmetric or uses non-standard surfaces.
