Mid- and far-infrared astronomy mission SPICA

Advances in Space Research, 2007
Abstract We present an overview and the current status of SPICA (Space Infrared Telescope for Cosmology and Astrophysics), which is an astronomical mission with a cryogenically cooled 3.5 m telescope optimized for mid- and far-infrared astronomy. Because of its high spatial resolution and unprecedented sensitivity in the mid- to far-infrared, SPICA ...

GaAs BIB photodetector development for far-infrared astronomy

SPIE Proceedings, 2004
GaAs photoconductive detectors offer an extended spectral response in the far-infrared (FIR) compared to presently available stressed Ge photoconductors. Furthermore, responsivity at wavelengths up to 330 microns can be reached without having to apply uniaxial stress close to the breaking limit on each pixel.

Filters for Far Infrared Astronomy

1972
In developing far infrared photometers for astronomical purposes one of the main problems is the efficient spectral filtering of the radiation. As a consequence of the unknown spectral distribution of the usually weak radiation of the objects, the filterbands must have a high transmission with steep edges; in addition a specified spectral band and ...
