UVscope is an instrument, based on a multi-pixel photon detector, developed
to support experimental activities for high-energy astrophysics and cosmic ray
research. The instrument, working in single photon counting mode, is designed
to directly measure light flux in the wavelengths range 300-650~nm. The
instrument can be used in a wide field of applications where the knowledge of
the nocturnal environmental luminosity is required. Currently, one UVscope
instrument is allocated onto the external structure of the ASTRI-Horn Cherenkov
telescope devoted to the gamma-ray astronomy at very high energies. Being
co-aligned with the ASTRI-Horn camera axis, UVscope can measure the diffuse
emission of the night sky background simultaneously with the ASTRI-Horn camera,
without any interference with the main telescope data taking procedures.
UVscope is properly calibrated and it is used as an independent reference
instrument for test and diagnostic of the novel ASTRI-Horn telescope.
