滨松光子学株式会社推出了一种封装在塑料封装中的全新微型 PMT，非常适合用于缩小医疗诊断设备和环境分析仪的尺寸。
全新微型 PMT 将于 2019 年 10 月 1 日发售。
滨松光子学株式会社现提供全新微型 PMT “R12900U”，采用微型塑料封装，可轻松地安装在电子电路板上，是世界上最小的光电倍增管。安装这种全新微型 PMT 作为光电检测器意味着环境分析仪、便携式医疗诊断设备等现在可以大幅缩小尺寸，以便在任何需要的地方使用，包括患者床边。
这种全新微型 PMT 自 2019 年 10 月 1 日起起售，主要面向国内外市场的医疗器械和分析仪器制造商。我们还在开发更小的微型 PMT，计划于明年春季开始发运样品产品。
该全新微型 PMT 将于 9 月 4 日（周三）至 6 日（周五）在 Makuhari Messe（日本千叶市的 Mihama-ku）举办的 JASIS 2019 展览会上展出 3 天。这是亚洲最大型的最新分析和科学仪器展览会。
特点
1) 小尺寸，体积减至普通微型 PMT 模块的 1/9
通过消除通常用于微型 PMT 模块的外围电路，该全新微型 PMT 的尺寸得以减小。它的尺寸仅为 14 mm×14 mm×3.5 mm (W×H×D)，体积减少到微型 PMT 模块的 1/9，同时降低了成本。该全新微型 PMT 将有助于增加设计自由度，允许外围电路和组件的灵活布局，以匹配客户设备的尺寸和形状。运行该全新微型 PMT 需要单独的外围电路。
2) 轻松安装在电路板上
全新微型 PMT 封装在塑料封装中，可轻松安装在电子电路板上。尺寸足够小，可以放在指尖上，易于操作。
