Mid-infrared wavelengths are less affected by atmospheric effects and can significantly enhance link uptime and range. This paper will discuss some of the recent advances in high-power, high temperature, high reliability mid-infrared Quantum Cascade Lasers and their potential application in highly ...
The far-infrared (20-410 cm-1) reflectivity of the quaternary alloy In1-xGaxAsyP1-y epitaxially grown and lattice-matched to an InP substrate has been measured for y=0.22 to 0.66. The lattice vibrational frequencies obtained from the data are in substantial agreement with previous Raman result...
Far-red light (FRL) occurs at the long-wavelength edge between VL and infrared light, encompassing wavelengths from 700 to about 800 nm. From:Encyclopedia of Biological Chemistry (Third Edition),2021 Add to Mendeley Also in subject area: ...

The central wavelength of far-infrared filter is generally within the range of 2.0um-25um. The film is coated with silicon wafer, germanium, sapphire, magnesium fluoride and calcium fluoride as the substrate. The peak value of the filter can reach more than 90%....
(2–7). Although these materials have good electrical conductivity, the long-wave cutoff wavelength of transparent area is limited to the mid-infrared band (λp < 5 μm). In addition, studies have reported the effect of the doping28and heating29on increasing theεoptof the dielectric...
With appropriate material combinations, a broad working range across the visible or near-infrared becomes attainable for both hyperbolic dispersions and highly elliptical dispersions36. The resolution of hyperlenses is essentially determined by the geometry, material loss and also the film quality. In ...
HIGH-RESOLUTION FOURIER TRANSFORM SPECTROSCOPY OF LANTHANUM IN Ar DISCHARGE IN THE NEAR-INFRARED A high-resolution spectrum of lanthanum has been recorded by a Fourier Transform spectrometer in the wavelength range from 833 nm to 1666 nm (6000 cmto 12,... F Güzel?Imen,G Ba?Ar,M Tamanis,...
Infrared heaters can be operated in vacuum or atmosphere.One classification of infrared heaters is by the wavelength bands of infrared emission. 1. Short wave or near infrared for the range from 780 nm to 1,400 nm, these emitters are also named bright because still ...
