The Carnegie Planet Finder Spectrograph (PFS) has been constructed for use with the Magellan telescopes at Las Campanas Observatory in Chile. PFS has been optimized for high-precision measurement of ...

The COMICS spectrograph consists of 5 arrays, each 320 pixels in the dispersion direction, separated by the equivalent of 250 pixels. The entire spectrum fits on a single array in low-resolution mode, ...

The Echelle spectrograph enables us to obtain high-resolution spectra by a comparatively wide entrance slit using the higher orders of an echelle grating. Because of the high order numbers, light from ...

Abstract: A grating spectrograph integrated monolithically for the first time in the InGaAsP system with a photodiode array for a dense WDM application is presented for the 1.5 mu m wavelength region.

THE USE OF A PLANE GRATING IN STELLAR SPECTRO-SCOPY.—In No. 5, vol. vi., of the Journal of the Royal Astronomical Society (Canada) there is an interesting note describing some preliminary tests, made ...

In a recent article published in Earth, Planets and Space, researchers developed the "hyperspectral camera for auroral imaging (HySCAI)" to study auroral phenomena. This instrument aims to capture two ...

A brand new spectrograph on the Gemini North telescope has seen first light, detecting elements in a dying star known as the Jewel Bug Nebula. When you purchase through links on our site, we may earn ...

Spectrographs are important tools for studying many biological and chemical processes and substances, from pigments to plant growth and nucleic acids to pharmaceuticals, providing information about ...

Abstract: A basic need of modern UV and x-ray astronomy is the capability to perform high resolution spectroscopy of faint stars. The use of modern grazing incidence optics can be coupled to high ...
