Shortwave infrared wavelength
SpletFLIR's shortwave infrared (SWIR) camera core provides outstanding image quality and performance over a wide range of imaging and light level conditions. Ideal for a variety of applications, including hyperspectral instrumentation, silicon inspection, electro-optical payloads, art restoration, and portable applications. SpletHgCdTe can also detect in the short wave infrared SWIR atmospheric windows of 2.2 to 2.4 µm and 1.5 to 1.8 µm. HgCdTe is a common material in photodetectors of Fourier transform infrared spectrometers. This is because of the large spectral range of HgCdTe detectors and also the high quantum efficiency.

SpletWhat is SWIR? Short-wave infrared (SWIR) light is typically defined as light in the 0.9 – 1.7μm wavelength range, but can also be classified from 0.7 – 2.5μm. Since silicon sensors have an upper limit of approximately 1.0μm, SWIR imaging requires unique optical and … SpletInfrared -A is classified as the “hottest” Infrared with temperatures up to 2,700C and wavelengths of 0.7 – 1.4 microns and is also called “Short-wave” or “Near” Infrared; Infrared – B is infrared with temperatures of 500 – 800C and wavelengths of 1.4 – 3 microns and is also called middlewave or “Medium” Infrared;
SpletTypically we define near infrared (NIR) from 780 nm to 1400 nm and shortwave infrared (SWIR) from 1400 nm to 3000 nm. But it is also common to refer to the entire range from 780 nm up to 3000 nm as NIR or SWIR. The NIR/SWIR region has multiple advantages, … Shortwave radiation (SW) is radiant energy with wavelengths in the visible (VIS), near-ultraviolet (UV), and near-infrared (NIR) spectra. There is no standard cut-off for the near-infrared range; therefore, the shortwave radiation range is also variously defined. It may be broadly defined to include all radiation with a wavelength of 0.1μm and 5.0μm or narrowly defined so as to include only radiation between 0.2μm and 3.0μm.
SpletThe Earth emits infrared radiation or longwave radiation. This follows directly from the electromagnetic energy spectrum and the respective temperatures of the Sun and Earth. The Sun emits radiation at a shorter wavelength than the Earth because it has a higher temperature, and Planck’s curve for higher temperatures peaks at shorter wavelengths.
