Optical design of WUVS instrument: WSO-UV spectrographs

SPIE Proceedings, 2016
World Space Observatory - Ultraviolet project is an international space observatory for spectroscopy and imaging in 115-310 nm spectral range. The WSO-UV telescope feeds in its focal plane two main instruments for spectroscopy (unit of spectrographs - WUVS) and imaging (field camera unit - FCU) as well as Fine Guidance System (FGS).

The Hector Instrument: optical design of the new higher-resolution spectrograph

Ground-based and Airborne Instrumentation for Astronomy VIII, 2020
The Hector instrument is the new multi-object facility at the Anglo-Australian Telescope. It consists of new-format hexabundle IFU’s, complex robotic positioner with magnetic system, unique sky-fibre system, guiding system, optical cable and two spectrographs. Light is captured at the telescope prime focus by optical fiber imaging bundles (hexabundles)

The SALT HRS spectrograph: instrument integration and laboratory test results

SPIE Proceedings, 2012
SALT HRS is a fibre-fed, high dispersion echelle spectrograph currently being constructed for the Southern African Large Telescope (SALT). In this paper we highlight the performance of key optical components, describe the integration tasks that have taken place and present some first light results from the laboratory.

Apollo 16 Far-Ultraviolet Camera/Spectrograph: Instrument and Operations

Applied Optics, 1973
A far-ultraviolet camera/speqtrograph experiment was designed and constructed for studies of the terrestrial upper atmosphere and geocorona, the interplanetary medium, and celestial objects from the lunar surface. The experiment was successfully operated during the Apollo 16 mission 21-23 April 1972. Discussed are the design and operating principles of

Integration of the instrument control electronics for the ESPRESSO spectrograph at ESO-VLT

SPIE Proceedings, 2016
ESPRESSO, the Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations of the ESO - Very Large Telescope site, is now in its integration phase. The large number of functions of this complex instrument are fully controlled by a Beckhoff PLC based control electronics architecture.

The Durham Cosmic Ray Spectrograph: I. The General Features of the Instrument

Proceedings of the Physical Society, 1962
An account is given in this paper of the general features of a cosmic ray spectrograph with a maximum detectable momentum of 26.5 GeV/c. Particular attention is given to the determination of the correction factors needed for accurate measurements of particle momenta. The instrument has an acceptance rate of 5000 particles per day.

The Goddard High Resolution Spectrograph: Instrument, goals, and science results

Publications of the Astronomical Society of the Pacific, 1994
The Goddard High Resolution Spectrograph (GHRS), currently in Earth orbit on the Hubble Space Telescope (HST), operates in the wavelength range 1150-3200 A with spectral resolutions (lambda/delta lambda) of approximately 2 x 10(exp 3), 2 x 10(exp 4), and 1 x 10(exp 3).

The infrared imaging spectrograph (IRIS) for TMT: instrument overview

2018
With the successful completion of our preliminary design phase, we will present an update on all design aspects of the IRIS near-infrared integral field spectrograph and wide-field imager for the Thirty Meter Telescope (TMT). IRIS works with the Narrow Field Infrared Adaptive Optics System (NFIRAOS) to make observations at the diffraction limit of TMT ...

Instrument physical model for the SOXS (Son Of X-Shooter) spectrograph

SPIE Proceedings, 2016
We present the proposal for the physical instrument model of the SOXS (Son OF X-Shooter) spectroscopic facility mainly devoted to the follow-up observation of transient sources. A dedicated suitable instrument to exploit the science of these transients is lacking, resulting in severe science “dissipation”.

Millimetre-scale spectrographs for next-generation photonic instrumentation

We present a set of ultra-compact spectrographs fabricated using two-photon polymerisation, each under 1 mm in length and printed directly onto an optical fiber. This fully integrated, alignment-free architecture enables extremely low-mass instrumentation with broad potential across astrophotonics, space systems, drone-based sensing, and quantum optics.
