Monochromators are an essential part of many spectrometers, important for a range of applications. This article describes what a monochromator is, how it works, the different types, what they are used ...

Directly bonded fused silica GRISM (Prism + Grating) with grating at the inner surface. Credit: Fraunhofer IAO Space agencies examine the extent of greenhouse gases in the air via prisms and ...

The oxygen bridges firmly connect the grating and prisms together, and the radiation in space cannot damage them. In addition, there is no intermediate layer, as in the case of adhesive, which would ...

Measure greenhouse gases from space Date: June 22, 2016 Source: Fraunhofer-Gesellschaft Summary: Space agencies examine the extent of greenhouse gases in the air via prisms and gratings in satellites.

Smaller gratings let much less light through, which limits the size of the grating. Prisms have their own set of issues, such as a limited wavelength range.

The effect of a diffraction grating is similar to that created by photonic crystal structures: the source for that gorgeous flash of iridescent color in peacock feathers, opals, and the wings of ...
