Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 9CJ(Z+;OM  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm w##^}nHOR  
Type: Double Bounces >oGiIYq  
The '****' denotes a possible internal focus u.,Q4u|!  
RMS is the RMS spot radius on axis at the primary wavelength. Zd!U')5/  
RMS values of 0.00 indicate that an accurate RMS !E2W\chi  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is X^s2BW  
non-rotationally symmetric or uses non-standard surfaces.
