Ghost Trace Data

Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm -fR:W{u  
Type: Double Bounces tXD$HeBB?  
The '****' denotes a possible internal focus $XBK_ 5  
RMS is the RMS spot radius on axis at the primary wavelength. ._mep\#.:  
RMS values of 0.00 indicate that an accurate RMS

could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is {zdMmpQF  
non-rotationally symmetric or uses non-standard surfaces.
