spectral regions

[′spek·trəl ‚rē·jənz]
(spectroscopy)
Arbitrary ranges of wavelength, some of them overlapping, into which the electromagnetic spectrum is divided, according to the types of sources that are required to produce and detect the various wavelengths, such as x-ray, ultraviolet, visible, infrared, or radio-frequency.

Edmund Optics[R] has extensive coating capabilities, and expertise in producing coatings for advanced diagnostic applications, harsh environment imaging assemblies, and applications throughout the ultraviolet (UV), visible (VIS), and infrared (IR) spectral regions. All optics are meticulously cleaned, coated, and inspected in a clean room environment, and subjected to the environmental, thermal, and durability requirements specified by our customers.
Kaplan noted that the radiation from different spectral regions are primarily emanating from different atmospheric layers, which can be used to retrieve the atmospheric temperature at different heights in the atmosphere.
Such materials display a plasmonic response in different spectral regions, as dictated by their free charge carrier density N.
This analysis identified 33 key variables for protein determination, concentrated in the spectral regions near 1021-1023 nm, 1025-1028 nm, 1031 nm, 1107 nm, 1110 nm, 1114 nm, 1212-1213 nm, 1215 nm, 1272-1286 nm, 1290-1291 nm, 1513-1524 nm, 1837-1847 nm, and 2091-2093 nm.
It should be noted that the proposed method is simply a "univariate" approach that does not consider combinations between spectral regions. Concomitant with the combination is a global optimization problem which corresponds to a much longer computation time even in small datasets.
Analysis of Variance (ANOVA) with Tukey's test was performed to evaluate the %RMSE attained based on different spectral regions over 100 training/test splits to determine if there is a significant different at 95% confidence level.
The observed signs of MCD effect within different spectral regions point to the fact that in this thin film garnet material, the octahedral magnetic sublattice was orienting itself in the direction of the magnetic field applied externally.
To understand the relative importance of the different spectral regions, much effort has been made over the years.
Consequently, the spectral regions and bands sensitive to yellow rust were found out (Fig.
