Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx d%ncI0f`  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm `b[@GGv  
Type: Double Bounces bg,VK1  
The '****' denotes a possible internal focus <V4"+5cJ8  
RMS is the RMS spot radius on axis at the primary wavelength. KRj3??b  
RMS values of 0.00 indicate that an accurate RMS P6 mDwR  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is boIFN;Aq"  
non-rotationally symmetric or uses non-standard surfaces.
