Automation of a plane grating spectrograph

A Zeiss model PGS-2 plane grating spectrograph was automated by replacing its photograph film detection system with an EGG-Reticon 1024S photodiode array (PDA) and by controlling the main instrument functions through the use of a home-made interface connected to a microcomputer. The array was cooled by four Peltier elements to allow integration of the emitted light for up to 40 s. The interface...

Photometric Calibrations for the Sirtf Infrared Spectrograph

The SIRTF InfraRed Spectrograph (IRS) is faced with many of the same calibration challenges that were experienced in the ISO SWS calibration program, owing to similar wavelength coverage and overlapping spectral resolutions of the two instruments. Although the IRS is up to ∼300 times more sensitive and without moving parts, imposing unique calibration challenges on their own, an overlap in phot...

A slit grating spectrograph for quantitative soft x-ray spectroscopy

In this article we describe a new slit grating spectrograph which is based on an e-beam written 10 000 linepairs/mm freestanding transmission diffraction grating. In combination with a thinned, back-illuminated charge coupled device ~CCD!, the spectrograph allows for real-time spectroscopy of laser-produced plasma x-ray sources within the wavelength region l51–20 nm. Calibration of grating and ...

Microshutters Arrays for the JWST Near Infrared Spectrograph

The Near Infrared Spectrograph (NIRSpec) for the James Webb Space Telescope (JWST) is a multi-object spectrograph operating in the 0.6-5.0 μm spectral range. One of the primary scientific objectives of this instrument is to measure the number and density evolution of galaxies following the epoch of initial formation. NIRSpec is designed to allow simultaneous observation of a large number of sou...

Calibration concept for the JWST Near - infrared Spectrograph ( NIRSpec )

This document provides a discussion of the basic calibration needs and calibration time consumption for the Near Infrared Spectrograph (NIRSpec) on JWST. The current version assumes that slits for multi object spectroscopy will be formed via a microelectromechanical system and that NIRSpec will carry internal continuum and line lamps.
