Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm (O$il  
Type: Double Bounces {ePtZyo0  
The '****' denotes a possible internal focus o- v#

RMS is the RMS spot radius on axis at the primary wavelength. GIvl|  
RMS values of 0.00 indicate that an accurate RMS m:D0O]2  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is [G",Yky  
non-rotationally symmetric or uses non-standard surfaces.
