Question G4Paraboloid Reflection 

Forum: Processes Involving Optical Photons
Date: 01 Jun, 2009
From: Greg Damhorst <Greg Damhorst>

Hello,

I'm trying to model an acrylic lightguide in Geant 4 (v 9.1). One section of this lightguide is a winston cone (http://scienceworld.wolfram.com/physics/WinstonCone.html), which I am trying to model using the G4Paraboloid class.

As shown in the attached visualization, internal reflection off the surface of this paraboloid doesn't appear to be behaving properly. Has anyone experienced this before? Any ideas how we might correct it?

Thanks,

Greg Damhorst
