Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm #BsW  
Type: Double Bounces !.*iw k`  
The '****' denotes a possible internal focus Hs$'0:  
RMS is the RMS spot radius on axis at the primary wavelength. 0'`S,  
RMS values of 0.00 indicate that an accurate RMS a$}N
W.  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is afx'  
non-rotationally symmetric or uses non-standard surfaces.
