Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx 8 `v-<J  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm h/QXPdV  
Type: Double Bounces KaLzg5is  
The '****' denotes a possible internal focus +r�  
RMS is the RMS spot radius on axis at the primary wavelength. f%A;`4`q  
RMS values of 0.00 indicate that an accurate RMS iOf<$f  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is o@_q]/Mh  
non-rotationally symmetric or uses non-standard surfaces.
