Journal Article
Small-scale structures in the far-infrared background
U. Herbstmeier,Péter Ábrahám,Dietrich Lemke,R. J. Laureijs,Ulrich Klaas,Kalevi Mattila,Christoph Leinert,Christian Surace,M. Kunkel +8 more
TL;DR: In this article, the authors examined the spatial characteristics of the infrared background emission with high spatial resolution and found that the fluctuations in the background emission limit the detection sensitivity of ISOPHOT for most of their observations.

The 10-200 micron spectral energy distribution of the prototype Narrow-Line X-ray galaxy NGC 7582
TL;DR: In this paper, the spectral energy distribution (SED) between 10 and 200 micron was obtained for the prototype Narrow-Line X-Ray Galaxy NGC 7582 with ISOPHOT, the photometer on board the Infrared Space Observatory.
Journal ArticleDOI
IR resonant filters for the wavelength region 30 - 200 μm.
D. Johannsmann,Dietrich Lemke +1 more
TL;DR: A series of UV-lithography-made cross-shaped mesh structures on polyimide substrates have been investigated as possible resonant filters for use in the middle and far-infrared.
Journal ArticleDOI
Cryogenic ratchet wheel drive for the ISOPHOT experiment
TL;DR: In this paper, an advanced cryogenic ratchet wheel drive has been developed based on experience from the GIRL project for the photometer experiment for ISO, and three of these wheels are equipped with filters, apertures and mirrors.
Proceedings ArticleDOI

TL;DR: In this article, the authors give an overview on the detailed design, prototyping and testing of those mechanisms comprising highest reliability in the cryo-vacuum (~ 35K) combined with minimal power dissipation (~ 5mW on average), ultimate position accuracy (ARIANE 5, ~ 60g) and a very long lifetime (~ 15 years) for ground tests and space operation under various environmental conditions.
