38 // 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.
