Devices for Flow cytometer.

Flow cells

For over 50 years we have manufactured glass vacuum devices such as photomultiplier tubes, which require special quartz glass processing, high accuracy, optical polish, etc. We have applied this extensive experience and knowledge to manufacturing flow cells.

PMT (photomultiplier tubes)

In the photosensor field, photomultiplier tubes (or PMT) are known to have particularly high sensitivity. PMT also have dozens of other advantages such as high-speed response time.

PMT modules

The PMT module is basically comprised of a photomultiplier tube to convert light into electrical signals, a high-voltage power supply circuit, and a voltage divider circuit to distribute the optimum voltage to each dynode, all assembled into a single compact case. In addition to these basic PMT modules, Hamamatsu also provides modules having various additional functions such as signal processing, cooling and interface to PC.

Si APD

Si APDs are high-speed, high sensitivity photodiodes having an internal gain mechanism, and can be used in measurements at very low light levels.

APD modules

C12703,C12703-01

These are high-speed, high-sensitivity photodetectors using an APD. An APD, a low-noise amplifier, and a bias power supply are assembled together in a compact case. Simply connecting to a low voltage DC power supply allows light measurements with an S/N level dozens of times higher than PIN photodiodes.

MPPC (SiPM)

The MPPC is one of the devices called silicon photomultipliers (SiPM). It is a photon-counting device using multiple APD (avalanche photodiode) pixels operating in Geiger mode. Although the MPPC is essentially an opto-semiconductor device, it has excellent photon-counting capability and can be used in various applications for detecting extremely weak light at the photon counting level. Various types of devices with different pixel sizes and package types are prepared.

MPPC modules

MPPC modules are photon-counting modules that contain an MPPC (multi-pixel photon counter) capable of detecting extremely low-level light. These modules deliver excellent photon-counting characteristics by extracting maximum MPPC performance.
