Asahi Kasei Microdevices (AKM) provides the infrared photo-diode (quantum-type infrared sensor) based on the manufacturing technology of compound semiconductor which has been developing with magnetometric sensor products.
Cooling process is not necessary and room temperature operation is possible, while the advantage of quantum type infrared sensors, such as a fast response and a direct-current output, remains.
This feature enhances ease of use, and makes small and thin size possible.

AKM provides sensor IC which integrates infrared sensor elements and other components such as a signal processing IC.

Technical Information

Classification of infrared sensors

Emission spectrum from object

The infrared rays are light of wavelength from 0.75 to 1000μm. The human body or any objects emit the infrared light, and its spectral irradiance depends on their temperature.
