Passive IR: this modality captures the thermal radiation of an object in the mid- wave infrared spectrum (MWIR: 3- 5μm) and the long -wave infrared spectrum ( LWIR 


IR is a type of electromagnetic radiation, a continuum of frequencies produced when atoms absorb and then release energy. From highest to lowest frequency, electromagnetic radiation includes

Dess vinkel i kombination med formen förhöjer det perifera skyddet och optimerar up Infrared waves, or infrared light, are part of the electromagnetic spectrum. People encounter Infrared waves every day; the human eye cannot see it, but humans can detect it as heat. A remote control uses light waves just beyond the visible spectrum of light—infrared light waves—to change channels on your TV. Generally, the infrared bands for inorganic materials are broader, fewer in number and appear at lower wavenumbers than those observed for organic materials.

The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. There are two tables grouped by frequency range and compound class. The infrared portion of the electromagnetic spectrum is usually divided into three regions; the near-, mid- and far-infrared, named for their relation to the visible spectrum. The higher-energy near-IR, approximately 14,000–4,000 cm −1 (0.7–2.5 μm wavelength) can excite overtone or combination modes of molecular vibrations . 2021-04-23 · What an infra-red spectrum looks like A graph is produced showing how the percentage transmittance varies with the frequency of the infra-red radiation. Note: The infra-red spectra on this page have been produced from graphs taken from the Spectral Data Base System for Organic Compounds ( SDBS ) at the National Institute of Materials and Chemical Research in Japan.

What is infrared photography? The human eye cannot see infrared light. It lies beyond the visible light spectrum. But you can take photographs with an infrared filter or infrared film, which produces intriguing effects, to peer into this world. Colors and textures take on unique properties when reflected with infrared light, also known as IR light.
