Question Optical photon refraction through a lens 

Forum: Processes Involving Optical Photons

From: Adam Glaser <Adam Glaser>

Hi everyone,

I was curious how GEANT4 can currently (or may be) possible to use for modeling optics accurately. Would it be possible to define a geometry solid/volume with a surface curvature defined analytically? I see that a sphere can be defined, but how difficult would it be to define an aspheric surface - such as those used in optical components and commercial packages, e.g. ZEMAX.

ZEMAX can export CAD files which could be parsed into GEANT4, but if I understand correctly this will tessellate the surface which is not desirable for accurate optics, and instead defining surfaces analytically with known constants would be ideal.

Thanks, Adam
