Absorption spectroscopy is a fundamental analytical technique widely used in various scientific disciplines, including chemistry, biology, and material science. It effectively analyzes substance ...

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 ...

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 ...

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

Each colour within the visible light spectrum has its own narrow band of wavelength and frequency. When white light passes through a coloured filter, all colours are absorbed except for the colour ...

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 ...

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 ...

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

"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 ...
