FEROS, the Fiber-fed Extended Range Optical Spectrograph for the ESO 1.52-m Telescope

FEROS is a fiber-fed bench-mounted prism-crossdispersed echelle spectrograph for the ESO 1.52-m telescope at La Silla. It works in quasi Littrow mode and in white pupil configuration. For the object and the nearby sky, the complete optical spectrum from 370–860 nm is recorded in one exposure with a resolving power of R = 48,000 by the use of a two-beam, two-slice image slicer. A first concept o...

Fiber-assisted single-photon spectrograph

We demonstrate the implementation of a fiber-integrated spectrograph utilizing chromatic group velocity dispersion (GVD) in a single-mode fiber. By means of GVD we stretch an ultrafast pulse in time in order to spectrally resolve single photons in the time domain, detected by single-photon counting modules with very accurate temporal resolution. As a result, the spectrum of a very weak pulse is...

A New Spectrograph Platform for Auroral Studies in Svalbard

A versatile spectrograph platform has been installed by University College London at the Adventdalen Observatory in Svalbard. The platform was primarily built to support the Southampton University study of proton aurora and smallscale auroral features. It has successfully recorded the spectral profile of the Doppler broadened H-beta emission line (486.1 nm) and observed the predicted red shifte...

Raman Imaging with a Fiber-Coupled Multichannel Spectrograph

Until now, spatially resolved Raman Spectroscopy has required to scan a sample under investigation in a time-consuming step-by-step procedure. Here, we present a technique that allows the capture of an entire Raman image with only one single exposure. The Raman scattering arising from the sample was collected with a fiber-coupled high-performance astronomy spectrograph. The probe head consistin...

Adaptive optics echelle spectrograph for radial velocity studies

Radial velocity studies represent the most successful method to date for the detection of extrasolar planets. Although radial velocity (vr ) measurement precision of 3 m s –1 is routinely achieved in some programs, it is important to understand and minimize sources of experimental error. Furthermore, velocity variations resulting from astrophysical processes contribute to velocity errors, and m...
