//    Class used in the definition of the Ultra setup consisting of:
//      - the UVscope detector
//      - an optional reflecting surface
//    Optical photons can reach the UVscope either directly or after reflection in the
//    surface, which can be polished or diffusing.
//    The main part of the UVscope definition is the Fresnel lens construction based
//    on the UltraFresnelLens class.
