The ESIS-II mission aims to capture high-speed “snapshot” images of the Sun’s transition region and corona. To achieve this, ...

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 ...

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.

Holographic concave grating design elevates Ocean Optics’ newest miniature spectrometer. Ocean Optics (www.OceanOptics.eu) has launched a family of aberration-corrected holographic concave diffraction ...

Imaging spectrometers represent a critical advancement in optical instrumentation, integrating high‐precision optical components with innovative design architectures to capture both spatial and ...

When we taught a class of first year chem/biochem majors about spectroscopy, we introduced them to it with a task. It was to dig through bins full of the things shown below (many of them 3D-printed ...

Today, astronomers seek to observe the faintest and most distant objects possible. Extremely Large Telescopes (ELTs), with apertures in the order of several dozen meters, are the next generation ...

IIIF provides researchers rich metadata and media viewing options for comparison of works across cultural heritage collections. Visit the IIIF page to learn more. This echelon diffraction grating came ...
