Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm G"(!5+DLy  
Type: Double Bounces ?6

The '****' denotes a possible internal focus  +yk

RMS is the RMS spot radius on axis at the primary wavelength. [ CY=  
RMS values of 0.00 indicate that an accurate RMS h&P[9:LH  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is `3Y+:!q  
non-rotationally symmetric or uses non-standard surfaces.
