The Practice of Spectrum Analysis with Hilger Instruments: including a Note on the various Types of Emission Spectra. Compiled by F. Twyman. Fourth edition. Contributors: Prof. E. N. da C.

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 ...

A research team from Skoltech and ITMO university has obtained tunable polariton emission at room temperature on CsPbBr3 ...

This causes line emission spectra to be produced, as shown below. This is not a continuous spectrum as only light of specific frequencies and specific colours are produced. Different types of ...

Abstract: Exoplanet emission spectra are often modelled assuming that the hemisphere observed is well represented by a horizontally homogenized atmosphere. However, this approximation will likely fail ...

The spectrometer works best in darkness, though the black panels help if turning off most of the lights is impractical. The black panels should block everything on the camera's right-side field of ...

Abstract: The arc emission spectra of two identical high-pressure dc capillary lamps (one with 2 atmospheres xenon, one with 2 atmospheres krypton) are measured and compared. The total efficiency, as ...

This code computes the full log-likelihood map for high-resolution planetary emission spectra cross-correlated with atmospheric emission models. It was specifically written for CFHT ESPaDOnS ...

A spectrum emission mask is a convenient solution for checking if a 5G millimeter-wave (mmWave) device meets relevant standard emissions for unwanted interference. The mask is a limit of power at ...
