Efficient light collector array

The invention relates to the technical field of scientific instruments, and in particular relates to an efficient light collector array. Incident and emitting apertures of a condenser are designed to be a regular hexagon, so as to realize incident surface gap-free arrangement. Dead areas of arrangement gaps of a cylindrical photomultiplier and signal loss of edge invalid areas of the photomultiplier are effectively prevented. Due to the fact that the incident aperture of the condenser is larger than the emitting aperture, the regular hexagon of the emitting aperture is just the inscribed hexagon of a valid light-sensitive circular area of the photomultiplier. Photons which should fall into the dead areas and the invalid areas are reflected by a compound paraboloid and are emitted from an emitting hole. The axis of the condenser coincides with the axis of the photomultiplier. The emitting hole closely contacts the light receiving surface of the photomultiplier. Photons emitted from the condenser fall into the
