Researchers from Tokyo Metropolitan University have developed a new dye that can strongly absorb second near-IR radiation and ...

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

Many atoms and molecules have distinct absorption lines in the 1,200–2,300-nm wavelength range. Optical absorption spectroscopy using various laser sources has been demonstrated to be a useful ...

This work reports the design of an efficient multiband UC system based on Ln3+/Yb3+-doped core-shell upconversion ...

These systems utilize laser light to detect specific gases by measuring the differential absorption of light at different wavelengths. Recent research has focused on enhancing the capabilities of ...

Through a series of experiments in transmittance and reflectance measurements, the team found that the solar cell had a broad ...

While the light is severely attenuated due to the scattering and absorption processes, it is nonetheless encoded with the spectroscopic signatures of the molecules encountered en route to the detector ...

"This is because when we change wavelengths to obtain the fingerprint ... "Unlike traditional setups limited to specific gases or single absorption peaks, we can achieve real-time monitoring ...

It measures the absorption of infrared light by a sample at different wavelengths to produce a spectrum that provides information about the sample's molecular structure and composition. Schematic ...

The intensity of these wavelengths is measured by detectors, which help analyze the optical properties of the sample based on its absorption and reflectance of light across different wavelengths. This ...

Coherent (COHR) introduces a new high-power F-theta lens for additive manufacturing, EV battery welding and laser cleaning. The new lens ...
