Si Photodiodes

These are used in a broad range of applications, such as measurement, optical communications, and information devices.

Photo ICs

Signal processing circuits are integrated with photodiodes to form sophisticated elements that are compact and offer low noise.

Image sensors

This self-scanning photodiode array was developed for use in multi-channel spectrophotometers and measuring instruments.

PSD (Position Sensitive Detectors)

PSDs are sensors that detect the position of a spotlight, using the surface resistance of the photodiode. They are primarily used in distance measurement.

Infrared detectors

We provide a wide variety of infrared detectors in order to meet a large range of applications needs, such as detection of human beings, moisture meters, gas analyzers, and radiation thermometers.

Light Emitting Diode (LED)

These are used in auto-focusing mechanisms in cameras, in optical switches, in optical fiber communications, and in many other applications.

Application products and modules

Hamamatsu Photonics has a full lineup of these products available, including photosensor amplifiers, and various types of drive circuits.

Optical communication devices

Light-receiving and light-emitting devices are used in fiber-optic communication and spatial light transmission.
