Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm oZAB_A)[-  
Type: Double Bounces (vTtDKp@

RMS is the RMS spot radius on axis at the primary wavelength. L|,!?cSAT  
RMS values of 0.00 indicate that an accurate RMS +u3=dj"[  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 9T1Z
