// Class used in the definition of the optical photons source
39
// A plane, circular source is used. Depending on the source position, optical
40
// photons may reach the UVscope directly or after reflection. By default direct
41
// incidence is used. The source parameters can be set directly in this class
42
// or through the GeneralParticleSource messenger class.
