Ghost Trace Data
File : C:\Program Files\ZEMAX - Beta\Samples\Sequential\Objectives\Cooke 40 degree field.zmx &^"m6  
Title: A SIMPLE COOKE TRIPLET.
Units are Millimeters.
Wavelength: 0.550000 μm rx<fjA%  
Type: Double Bounces p
E#0949  
The '****' denotes a possible internal focus 4R.#=]F  
RMS is the RMS spot radius on axis at the primary wavelength. !nVuvsbv  
RMS values of 0.00 indicate that an accurate RMS H Zc;.jJ  
could not be computed, usually due to ray errors.
This analysis may be inaccurate if the system is xK f+.6 wz  
non-rotationally symmetric or uses non-standard surfaces.
