Hamamatsu Photonics made an announcement on successful development of first commercially workable GaN (gallium nitride) transmission photocathode that can be used for fast detection of extremely weak UV light signals. Hamamatsu is aiming for tripling the quantum efficiency of this newly developed photocathode in comparison to conventional CsTe (cesium telluride) photocathodes before its commercialization in spring of 2011, for its use in new image intensifiers.The newly developed GaN photocathodes will be ideal in applications such as semiconductor inspection and Raman spectroscopy.
