IR (Infrared) photodetector chips are semiconductor devices that detect infrared radiation and convert it into an electrical signal. These chips are designed to be sensitive to a specific range of IR wavelengths and are commonly used in a variety of applications such as remote sensing, spectroscopy, and thermal imaging.
IR photodetectors are typically made of semiconductor materials such as silicon or germanium, which have the ability to absorb infrared radiation and produce a corresponding electrical signal. The absorption of IR radiation causes electrons in the semiconductor material to be excited to a higher energy state, which generates a current in the detector.
There are several types of IR photodetectors, including photovoltaic, photoconductive, and thermoelectric. Photovoltaic detectors generate a voltage when exposed to IR radiation, while photoconductive detectors increase their conductivity when exposed to IR radiation. Thermoelectric detectors use the temperature change caused by the absorption of IR radiation to generate an electrical signal.
IR photodetectors are used in a wide range of applications, such as in night vision systems, gas and flame detection, and temperature measurement. They are also used in fiber optic communication systems to convert infrared signals into electrical signals for transmission.
We offer IR detector chips with wavelength range 1-5um that are used for various scientific and industrial applications. Our IR detector chips are used in the fields of chemistry, science, materials analysis and measurement, communication. The chips are available in the form of bare dice as a single pixel, pixel array on one die and linear array with fine pitch pixels.
