Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx [S`Fm>,  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm *i7-_pT  
Type: Double Bounces 7,9zj1<  
The '****' denotes a possible internal focus .|kp`-F51  
RMS is the RMS spot radius on axis at the primary wavelength. t9 id^  
RMS values of 0.00 indicate that an accurate RMS 4~:D7",Jn  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is {
