Hamamatsu Photonics introduces a new micro PMT encapsulated in a plastic package ideal for downsizing medical diagnostic devices and environmental analyzers

Hamamatsu R12900U

Hamamatsu Photonics now offers a new micro PMT “R12900U” housing the world’s smallest photomultiplier tube in a miniature plastic package designed to easily mount on electronic circuit boards. Installing this new micro PMT to serve as a photodetector means environmental analyzers, portable medical diagnostic devices and so on can now be drastically downsized for convenient use anywhere needed including patient bedsides.

Hamamatsu - R12900U

This new micro PMT is available for sale starting from October 1, 2019, mainly for medical device and analytical instrument manufacturers in domestic and overseas markets. We are also developing an even smaller micro PMT, aiming to start shipping sample products next spring.
