:1,xse  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 1y}tPkOe7O  
Type: Double Bounces kQQhZ8Ch  
The '****' denotes a possible internal focus w6FVSU]sY  
RMS is the RMS spot radius on axis at the primary wavelength. nMU[S+  
RMS values of 0.00 indicate that an accurate RMS 'ghwc:Og|%  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is {H[3[  
non-rotationally symmetric or uses non-standard surfaces.
