Scientists from the UK and China have developed a lateral-graded multilayer grating that addresses a key challenge in tender X-ray RIXS technique. Demonstrated at the I21 beamline in Diamond Light ...

ITOH Satoshi / Nagoya University (At the time: Dept. of Space Astronomy and Astrophysics, ISAS) Immersion echelle gratings are small, high-dispersion elements used in optical-infrared astronomy for ...

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 ...

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 ...

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.

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 ...
