Products

si_photodiode

Si photodiodes

Silicon photodiodes with high sensitivity and low dark current, as well as silicon PIN photodiodes suitable for high-speed applications.

ingaas_photodiode

InGaAs photodiodes

InGaAs photodiodes for near-infrared light detection. Features include high speed, high sensitivity, low noise, and spectral responses ranging from 0.5 μm to 2.6 μm. Suitable for a wide range of applications including optical communication, analysis, and measurement.

k_thumb_si_apd

Si APDs

Silicon APDs provide high sensitivity ranging from UV to NIR for low light detection at high speeds.

mppc

Multi-Pixel Photon Counters (MPPCs/SiPM)

Our Multi-Pixel Photon Counter (MPPC), also known as silicon photomultiplier (SiPM), is a solid state photomultiplier comprised of a high density matrix of Geiger-mode-operated avalanche photodiodes also known as SPAD (single-photon avalanche photodiode). These SPADs have high internal gain which enable single photon detection. The Hamamatsu SiPM features low dark count, high photon detection efficiency, excellent timing resolution, low bias voltage operation, ruggedness, resistance to excess light, and immunity to magnetic fields. They are well-suited to single photon counting and other ultra-low light applications.

image_sensor

Image sensors

We offer over 200 standard linear and area image sensors covering the short wavelength infrared (SWIR), near infrared (NIR), visible (VIS), ultraviolet (UV), and X-ray regions. With a broad selection from high speed, high sensitivity to wide dynamic range, our image sensors are suitable for different applications including spectroscopy analysis using spectrometers, industrial imaging such as machine vision cameras, microscopy, and distance measurements. We also provide supporting electronics such as easy-to-use driver circuits for sensor evaluation and driver modules for OEMs. Customizations are available for specific applications and requirements.

photo_ic

Photo IC

The photo IC is an intelligent optical sensor with diverse functions and integrates a photodiode with signal processing IC in the same package.

k_thumb_ir_detectors

Infrared detectors

Sensors and modules for infrared light detection.

color_sensor

Color sensors

Devices sensitive in the red, green, and blue spectral regions.

psd_position_detection_element

Position-sensitive detectors (PSDs)

PSDs are optoelectronic position sensors that utilize photodiode surface resistance. Unlike discrete element detectors such as CCDs, PSDs provide continuous position data, high position resolution, and high-speed response.

x_ray_flat_panel_sensor

X-ray flat panel sensors

X-ray flat panel sensors that combine a large-area CMOS image sensor and a fiber optic plate with scintillator (FOS). Can acquire high-definition, megapixel-level digital video and still images without distortion. With its thin profile and light weight, a flat panel sensor is easy to install into other equipment.
