Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx LuVL<W  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm 3Pvz57z{  
Type: Double Bounces M5 ^qc  
The '****' denotes a possible internal focus G+<id1  
RMS is the RMS spot radius on axis at the primary wavelength. |-z"6F r-  
RMS values of 0.00 indicate that an accurate RMS *E+VcU  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is 8+H 0  
non-rotationally symmetric or uses non-standard surfaces.
