Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 2$1rS}}  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 9iS3.LCfX  
Type: Double Bounces %$sWNn  
The '****' denotes a possible internal focus |G%MiYd  
RMS is the RMS spot radius on axis at the primary wavelength. ~xvQ?c?-  
RMS values of 0.00 indicate that an accurate RMS :I<%.|8  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 1egryp  
non-rotationally symmetric or uses non-standard surfaces.
