Hamamatsu Photonics introduces a new micro PMT encapsulated in a plastic package ideal for downsizing medical diagnostic devices and environmental analyzers.
This new micro PMT goes on sale on October 1, 2019.

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.
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.
This new micro PMT will be on display at the JASIS 2019 exhibition held in Makuhari Messe (Mihama-ku, Chiba-city, Japan) for 3 days from September 4 (Wed) to 6 (Fri). This is Asia’s largest exhibition of the latest in analytical and scientific instruments.

MicroPMT

Features

1) Small size, volume slashed to 1/9th that of ordinary micro PMT modules

The size of this new micro PMT was reduced by eliminating the peripheral circuits normally used in micro PMT modules. It has dimensions of only 14 mm×14 mm×3.5 mm (W×H×D) and volume was reduced to 1/9th that of micro PMT modules while keeping the cost down. This new micro PMT will help increase design freedom to allow flexible layout of peripheral circuits and components to match the size and shape of customer equipment. The peripheral circuits are separately required to operate this new micro PMT.
 

2) Easily mounts on circuit boards

New micro PMT is encapsulated into a plastic package designed to easily mount on electronic circuit boards. The size is small enough to fit on a fingertip, making it easy to handle.
