The wavelength-tunable laser only scans wavelengths near the latest wavelength of each FBG sensor. The scanning range is constantly updated to achieve wavelength tracking, and the FBG demodulator ...

You can switch between green ... range for red light therapy (around 633 nanometers for red light and 830 nanometers for near-infrared light)," Ellis reports. Not all devices advertise their ...

The latest findings build on previous research by the same group of astronomers, who also detected carbon dioxide and methane within the planet’s atmosphere using Webb’s Near-Infrared Imager ...

“This is an independent line of evidence, using a different instrument than we did before and a different wavelength range of light, where there is no overlap with the previous observations. The ...

Paulson School of Engineering and Applied Sciences (SEAS) have created a compact laser that emits extremely bright, short pulses of light in the “useful” mid-infrared wavelength range ... The device ...

The earlier, tentative, inference of DMS was made using JWST’s NIRISS (Near ... Infrared Instrument) in the mid-infrared (6-12 micron) range. “This is an independent line of evidence, using a ...

As part of InSeKT, Fraunhofer IPMS will be evaluating photodetectors for the near-infrared wavelength range. These are used, for example, in material analysis and recycling and even enable analysis ...

Furthermore, the goal of a data-supported evaluation of photodetectors for the near-infrared wavelength range is being pursued. These are used, for example, in material analysis and recycling and ...

The device can make what's called an optical frequency comb ... carbon dioxide and methane absorb mid-infrared light efficiently, this wavelength range has been an important tool in monitoring ...
