double beam scanning IR instrument that makes use of a diffraction grating in a monochromator to disperse the different wavelengths of light. The key components are the light source, entrance slit, grating and detector. Another type of IR spectrometer is a Fourier Transform (FT) spectrometer. In the FT spectrometer, an interferometer is used instead of a diffraction grating.

850nm is closer to the visible spectrum, and it's much easier to see a dull red glow in darkness. The first low-cost spectrophotometer capable of recording an infrared spectrum was the Perkin-Elmer Infracord produced in 1957. This instrument covered the wavelength range from 2.5 μm to 15 μm (wavenumber range 4,000 cm −1 to 660 cm −1). "Infrared" covers a pretty broad range, from wavelengths that are not-quite-visible to wavelengths that are practically microwaves.

The units that are typically used for infrared spectroscopy are wavenumbers (which is cm -1).

name to that range, for example, the ultraviolet spectrum, visible spectrum, infrared spectrum, microwaves, and radio, to name a few. Some spectral ranges of

Further analysis (below) will show that this spectrum also indicates the presence of an aldehyde function, a phenolic hydroxyl and a substituted benzene ring. The inverted display of absorption, compared with UV-Visible spectra, is characteristic.

Infrared radiation, that portion of the electromagnetic spectrum that extends from the long wavelength, or red, end of the visible-light range to the microwave range. Invisible to the eye, it can be detected as a sensation of warmth on the skin.

Hyperspectral imaging (IR) IR skanning (Hyperspectral imaging). •Samlar information SWIR Short-Wavelength InfraRed: 1,0 -2,5 μm.

LEDs and Laser detectors are common devices used in all the IR based products. It has wavelength range from 700 nm to 1 mm. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance) on the vertical axis vs. frequency or wavelength on the horizontal axis. Typical units of frequency used in IR spectra are reciprocal centimeters (sometimes called wave numbers), with the symbol cm −1. The region from 8 to 15 microns (µm) is referred to by Earth scientists as thermal infrared since these wavelengths are best for studying the longwave thermal energy radiating from our planet. LEFT: A typical television remote control uses infrared energy at a wavelength around940 nanometers.
