Ultraviolet and visible imaging and spectrographic imaging instrument
Applied Optics, 1994The Ultraviolet and Visible Imaging and Spectrographic Imaging experiment consists of five spectrographic imagers and four imagers. These nine sensors provide spectrographic and imaging capabilities from 110 to 900 nm. The spectrographic imagers share an off-axis design in which selectable slits alternate fields of view (1.00° × 0.10° or 1.00° × 0.05°)

Spectrograph Instrumental Profiles - Dependence on Dispersion
Publications of the Astronomical Society of the Pacific, 1982Spectrograph instrumental profiles (including stray light far away from the central peak) have been measured in blue and red light for the three cameras in the coude spectrograph of the 1.52-m telescope at Observatoire de Haute-Provence. The different dispersions 0.7, 1.2, and 2.0 nm mm-1 are obtained using the same ruled diffraction grating.

New Instrumentation for Making Spectrographic Pictures of Speech
The Journal of the Acoustical Society of America, 1963Communication by speech involves the production and perception of elements of an acoustic code. This code can be made visible in pictures which show certain spectral patterns existing in the sound signals. A new instrumentation has been developed for making spectrographic pictures of large quantities of speech.

A Modern Approach to Sound Spectrograph Instrumentation
The Journal of the Acoustical Society of America, 1970A new sound spectrograph has been developed that features direct analysis from a prerecorded tape plus several new features that facilitate ease of operation and provide a higher degree of reliability and consistency. The design uses a tape scanner that repeats any 2.5-sec segment of tape for spectrographic analysis, and includes an automatic tape ...

A projection instrument for the analysis of spectrographic plates
Journal of Scientific Instruments, 1934The paper describes the design of an instrument for examining spectrographic plates by projecting them optically, under a magnification of × 10, on to a white horizontal surface. The plate is placed on a stage adjoining this surface, and can be easily adjusted by the observer while examining the image.

The X-shooter Spectrograph: A Second Generation Instrument for the VLT
Chinese Journal of Astronomy and Astrophysics, 2006X-shooter is a spectrograph designed to feed the Cassegrain focus of the VLT. It may cover in a single exposure the spectral range from the UV to the H band with possible extension to the K band. The instrument is constituted by three arms, blue, visible and near-infarred, with optimized optics, coatings, dispersive elements and detectors.

OSIRIS tunable imager and spectrograph for the GTC. Instrument status
SPIE Proceedings, 2003OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) is the optical Day One instrument for the 10.4m Spanish telescope GTC to be installed in the Observatorio del Roque de Los Muchachos (La Palma, Spain). This instrument, operational in mid-2004, covers from 360 up to 1000 nm. OSIRIS observing modes include direct imaging with
