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.

Xenon lamps / mercury-xenon lamps

Xenon lamps emit a continuous spectrum with high luminance and high color temperature, ranging from the UV to visible to infrared range.

Si photodiodes


Featuring high sensitivity and low dark current, these Si photodiodes are specifically designed for precision photometry and general photometry/visible range.



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

Infrared detectors


Detectors with sensitivity to wavelengths above 1 µm. Careful selection of material combinations allows offering a variety of types that cover a broad spectral range.
