The Solid State Division of Hamamatsu Photonics provides many types of opto-semiconductors used in wide applications ranging from medical and scientific fields to communications, industry and general electronics.

Si photodiodes manufactured based on our advanced semiconductor process technologies cover a broad spectral range from the near infrared to ultraviolet and even to high-energy regions.

The APD (avalanche photodiode) is a high sensitivity photodiode that operates at high speeds and high gain by applying a reverse bias.

The MPPC is a new type of photon counting device made up of multiple APD (avalanche photodiode) pixels operated in Geiger mode and available in room temperature operation.

Hamamatsu Photonics has developed and manufactured image sensors with high sensitivity and a wide dynamic range that are ideal for measurement applications in physics, chemistry and industry.

X-ray image sensors consisting of a CCD image sensor or photodiode array that is optically coupled to a FOS (FOP coated with Scintillator material)

The photo IC is an intelligent optical sensor with diverse functions and integrating a photodiode with signal processing IC in the same package. Phototransistors are also provided.

Spectral response of these sensors is close to that of the human eye.

We offer a variety of sensors and modules for LCD color monitoring and simple color detection.

PSD (Position Sensitive Detector) is an optoelectronic position sensor utilizing photodiode surface resistance.

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

Light emitting diodes (LEDs) are opto-semiconductors that convert electric energy into light energy. Compared to laser diodes (LDs), LEDs offer advantages such as lower cost and longer service life.

X-ray flat panel sensor using the world's largest CMOS image sensor combined with a FOS. Delivers higher S/N, higher speed and wider dynamic range compared to flat panel sensors using amorphous materials.

HAMAMATSU mini-spectrometers are polychromators integrated with optical elements , an image sensor and a circuit.Light to be measured is guided into the entrance port of ｔhrough an optical fiber and the spectrum measured with the built-in image sensor is output from the USB port to a PC for data acquisition.

By merging technologies in the opto-semiconductor, optics, assembly, testing and measurement, Hamamatsu Photonics can now offer a full line-up of transmitter/receiver devices for optical communications.

We are using our own in-house process and packaging technology to develop automotive devices that are highly reliable even over a wide operating/storage temperature range.

We offer a variety of application-specific products using opto-semiconductors and circuit modules to make opto-semiconductors easy to use.
