Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx S{)'1J_0  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm *iujJi  
Type: Double Bounces fngk<$lvg  
The '****' denotes a possible internal focus U9yR~pw  
RMS is the RMS spot radius on axis at the primary wavelength. (k>I!Z/&2  
RMS values of 0.00 indicate that an accurate RMS @4j!M1}4  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is hgF4PdO1e  
non-rotationally symmetric or uses non-standard surfaces.
