An infrared photodetector known as a quantum well infrared photodetector (QWIP) absorbs photons using electronic intersubband transitions in quantum wells.
The energy difference between the first and second quantized states of the quantum well infrared photodetector’s quantum wells must match the energy of the incoming infrared photons in order for it to be employed for infrared detection.
Gallium arsenide, which is frequently used in smartphones and high-speed communications devices, is the material used to make QWIPs.The energy levels of the QWIP can be tuned to absorb radiation in the infrared region between 3 and 20 m depending on the material and quantum well design.
One of the most basic quantum mechanical device structures, QWIPs are capable of detecting mid- and long-wavelength infrared radiation.
Their great pixel-to-pixel homogeneity, stability, and operability are well-known. Infrared detectors typically function by sensing the radiation that an object emits, and the intensity of the radiation depends on the temperature, proximity, and size of the object.
Because QWIPs are based on the optical transition within a single energy band, they are independent of the band gap of the detecting material, unlike the majority of infrared photodetectors. It can therefore be used to identify objects with radiation of considerably lower energy than was previously feasible.
The Global QWIP camera market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
A high performance thermal imager that can see and precisely locate the source of SF6 and other uncontained QWIP camera by Gas DetectIR cameras. Gas DetectIR LW infrared camera. features a 3.5″ (640 x 480) LCD screen that can be rotated and an HD OLED tiltable viewfinder.
The camera’s small weight makes it ideal for quick on-site or distant surveillance. The camera’s small weight makes it ideal for quick on-site or distant surveillance.
