Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

Lighting and display manufacturers must ensure their products are consistent in their light output, making them reliant on effective quality control methods. Their products must be validated, and ...

Spectrometer optics involves measuring light intensity by means of a specialized analytical tool called a spectrometer which separates light by wavelength. Spectrometers are used for a variety of ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

In summer 2025, the European Space Agency ESA plans to launch the MTG-S1 satellite from the third generation of the Meteosat series. The geostationary satellite will significantly improve the accuracy ...

Hamamatsu Photonics has introduced a UV model of its ‘micro’ spectrometer series. C16767MA is sensitive across 190 to 440nm with a typical resolution of 5.5nm (FWHM, so ±2.25nm to 50%). Update: scroll ...
