   I have a model (in Zemax) of array of point sources (perpendicular to z   
   direction) followed by a lens (Non-Sequential Mode) I want to capture the   
   output from the lens by an aperture ( or even a detector )having a certain   
   acceptance angle .   
   I dont know how to specify an acceptance angle for the aperture in   
   non-sequential mode (I want this acceptance angle to be for the aperture only   
   not for the whole design as I want to model point sources @ the start of   
   system)?
