Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx $[j-C9W  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm Yr5iZ~V$  
Type: Double Bounces +d@v AxP  
The '****' denotes a possible internal focus aZI>x^X  
RMS is the RMS spot radius on axis at the primary wavelength. Y_$^:LG  
RMS values of 0.00 indicate that an accurate RMS *4-r`k|@>/  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is +Y^-e.UO  
non-rotationally symmetric or uses non-standard surfaces.
