Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx uo%P+om_}  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm EOj"V'!  
Type: Double Bounces Z<[<n0o1  
The '****' denotes a possible internal focus bNs4 5hDP  
RMS is the RMS spot radius on axis at the primary wavelength. @mP]*$00  
RMS values of 0.00 indicate that an accurate RMS x!LQxoNF  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is a8k;(/  
non-rotationally symmetric or uses non-standard surfaces.
