Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm GUJx?V/[  
Type: Double Bounces Yfs60f  
The '****' denotes a possible internal focus |ILj}4ZA7  
RMS is the RMS spot radius on axis at the primary wavelength. -Wb/3X  
RMS values of 0.00 indicate that an accurate RMS fiES6
VL  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is ezgP\ct  
non-rotationally symmetric or uses non-standard surfaces.
