What is the spectral range of the NIR wavelength?

800 to 2,500 nm
Near-infrared light generally refers to light within the wavenumber range of 12,500 to 4,000 cm-1 (wavelengths from 800 to 2,500 nm) (see Fig.

What can NIR detect?

NIR spectroscopy can be used for product identification, classification and quality control, as well as for the determination of product properties (chemical and physical) and component concentrations in process applications, all with the object of rapid analysis.

What is the difference between NIR and MIR?

MIR spectroscopy allows the identification of fundamental vibrational transitions and comprises the spectral range from 2500 to 50,000 nm, while the NIR spectra, the spectral range from 780 to 2500 nm, which contains overtone information and combinations of these vibrations, being more difficult to be interpreted (Reid …

What does NIR spectroscopy measure?

NIR spectroscopy measures light that is scattered off and through sample material, and this can rapidly determine the material’s properties. This process has no effect on the material itself.

What is frequency range of infrared radiation?

Infrared radiation (IR radiation for short) describes electromagnetic waves in the spectral range between visible red light and longer-wave microwave radiation (also known as terahertz radiation). Infrared (IR) has wavelengths λ between 780 nm and 1 mm, which corresponds to a frequency range from 300 GHz to 400 THz.

What NIR means?

Near-infrared, a region within the infrared part of the electromagnetic radiation spectrum.

How does mid-infrared spectroscopy work?

2.1 Mid-Infrared Spectroscopy MIR spectroscopy relies on light absorption. Incident IR light upon a sample causes biochemical bonds to vibrate. Vibrational modes of molecule thereby cause specific amounts of energy from the incident IR beam to be absorbed, reducing the intensity of the subsequently detected IR beam.

How does NIR measure protein?

A rapid test method was developed using near-infrared (NIR) spectroscopy as a compliment to current protein determination by the Dumas combustion method. The NIR method was found to be a rapid, low-cost, and green (no use of chemicals and reagents) complimentary technique.

Why we are using KBr in FTIR?

KBr is used as a carrier for the sample in IR spectrum and it is optically transparent for the light in the range of IR measurement. So that no interference in absorbence would occur. KBr, has a transmittance of 100 % in the range of wave number (4000-400 cm-1).

What is NIR light?

Infrared Light (IR) is the light found just past what is visible to the human eye. Near-Infrared Light (NIR) is the section of electromagnetic radiation (EMR) wavelengths nearest to the normal range but just past what we can see. Visible light is the smallest section of the electromagnetic (EM) radiation field.

What is the frequency of an infrared wave with a wavelength of 650?

4.61×1014Hz.

What is NIR light source?

NIR light, which ranges from 750 to 2500 nm, is used in several life science and biomedical applications because it exhibits less intrinsic absorption and inherently less scattering than using ultraviolet (UV) and visible light.
