The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

Diffraction gratings are beautiful things, bending transmitted and reflected light and splitting it into its component wavelengths to create attractive iridescent rainbow patterns. It’s the same ...

THE investigation of the spectrum of helium in the extreme ultra-violet, on which I have been long engaged, and which had pretty nearly come to a standstill for want of an untarnished diffraction ...

As stated in the article titled ‘An Introduction to a Spectrometer: The Slit’, a spectrometer is an imaging system that maps a plurality of monochromatic images of the entrance slit onto the detector ...

THE researches of Schumann led him to extend the spectrum to the neighbourhood of wave-length 1250. His limiting wave-length was determined by the absorption of the fluorite which formed a necessary ...
