While this is not exactly image sensor news, but Hamamatsu Photonics announced a successful development of an ultra-compact, next-generation μPMT (Micro photomultiplier tube). The μPMT is the world’s first PMT to be fabricated through the use of semiconductor processes for MEMS devices. Its prototype is thinner than the smallest PMT that Hamamatsu currently offers. By comparison, the μPMT has only 1/7th the volume and 1/9th the weight. Due to this extremely small size, it is expected that μPMTs will contribute to the development of more compact instruments for medical diagnostics, environmental monitoring, and applications in many other fields.
The μPMT is designed for mass production. Promotion with samples of the uPMT is scheduled to start for research & development in January 2011.
