The James Webb Space Telescope (JWST) is a passively cooled, 6.5m aperture class telescope, optimized for diffraction-limited performance in the near-infrared wavelength region (1 - 5 μm). JWST will be capable of high-resolution imaging and spectros

In 2011 NASA and ESA plan to launch the James Webb Space Telescope (JWST) as dignified successor of the Hubble Space Telescope. Three scientific instruments will cover the wavelength regions in the near-infrared (0.6-5μm, NIRCam and NIRSpec) and in

The feasibility of a compact Fourier-Transform-Imaging-Spectrometer (FTIS) for small satellite planetary and terrestrial remote sensing missions has been studied under ESA contract. The feasibility of this instrument concept was demonstrated by bread

An imaging FTS would be capable of carrying out many of the programs in the DRM, namely all those which require imaging and/or low spectral resolution wide field/multi-object spectroscopy. We review the DRM science areas, describing the relevance of

An Integral Field and Multiobject Spectrograph (IFMOS) for NGST has been studied for the European Space Agency by a European consortium. This paper describes the design of the integral field unit (IFU), the optical system which divides up the 2D fiel

A near and a mid infrared imaging camera for the NGST are presented, which were studied under ESA contract. Imaging in the 1 to 5 microns domain, possibly extended to 0.6 microns is a strong requirement for the core programs identified for NGST. Our
