A introduction to the basics of NIR spectroscopy and its chemical analysis capabilities across a variety of industries. ►More about near-infrared spectroscopy
Thewavelengthand color of the light produced depend on the material used in the diode. Infrared LEDs use material that produces light in the infrared part of the spectrum, that is, just below what the human eye can see. Different IR LEDs may produce infrared light of differing wavelengths, j...

JWST is an infrared telescope, meaning it "looks" at the universe in wavelengths of light that are longer than that of red light, which has the longest wavelength we can detect with our eyes. You may like Fiery James Webb Space Telescope image shows the early days of star formation James ...
Infrared is typically subdivided into multiple spectral regions, or bands, based on wavelength. However, there is no uniform definition of each band's exact boundaries. Infrared is commonly separated into near-, mid- and far-infrared. It can also divide into the following five categories: ...
The effect of EMF exposure on biological systems depends on the wavelength (frequency) and energy of the electromagnetic source. ??? of ionizing radiation (IR) is a high frequency electromagnetic wave (X rays and gamma rays), it has enough photonic energy to electrons of atoms or molecules ...
There are 5 sub-divisions of IR: 1. Near-infrared: Wavelength 0.75-1.4um Frequency 214-400 THz Temperature 3,864-2,070 K 2. Short-wavelength...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your tough...
Similar to the visible light spectrum, which ranges from violet (the shortest visible-light wavelength) to red (longest wavelength), infrared radiation has its own range of wavelengths. The shorter "near-infrared" waves, which are closer to visible light on the electromagnetic spectrum, don't em...
This is in contrast to the eye- hazardous portion of the optical spectrum of 400 - 1400 nm (visible and near infrared) where the anterior portions of the eye have high transmittance and refractive power. Irradiance levels are typically 5 orders of magnitude greater at the retina than at the...
The polarization increases with wavelength at the larger phase angles. Mie theory calculations of the polarization from a grain size distribution based on measurements by the Giotto spacecraft indicate that no single component fits the data; a two-component model is needed. The two components that ...
