  ASTRI (Astrofisica con Specchi a Tecnologia Replicante Italiana), is a
flagship project of the Italian Ministry of Education, University and Research
whose main goal is the design and construction of an end-to-end prototype of
the Small Size of Telescopes of the Cherenkov Telescope Array. The prototype,
named ASTRI SST-2M, will adopt a wide field dual mirror optical system in a
Schwarzschild-Couder configuration to explore the VHE range of the
electromagnetic spectrum. The camera at the focal plane is based on Silicon
Photo-Multipliers detectors which is an innovative solution for the detection
astronomical Cherenkov light. This contribution reports some preliminary
results on the evaluation of the optical cross talk level among the SiPM pixels
foreseen for the ASTRI SST-2M camera.
