Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm ge&!GO  
Type: Double Bounces oHethk  
The '****' denotes a possible internal focus ukee.:{  
RMS is the RMS spot radius on axis at the primary wavelength. Is ( Ji  
RMS values of 0.00 indicate that an accurate RMS R36A_  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is .Ax]SNZ+:A  
non-rotationally symmetric or uses non-standard surfaces.
