Abstract
In the context of the development of novel Thick GEM based detectors of single photons, the high resolution optical system, nicknamed Leopard, providing a detailed surface scanning of the Thick GEM electron multipliers, has been used for a set of systematic measurements of key Thick GEM properties. These results are reported and discussed. They confirm by direct observation Thick GEM properties previously inferred by indirect measurements and answer to relevant questions related to the use of Thick GEMs as photocathode substrates in novel gaseous photon detectors.
