Bandpass interference filters for very far infrared astronomy
Infrared Physics, 1980Abstract Three bandpass filters have been constructed for use with a 0.3K bolometer. The center frequencies and bandwidths of the filters are chosen to correspond with the 1, 2 and 3 mm atmospheric windows. The filters are formed of resonant metallic grids separated by air spacers.

Balloon-Borne Telescopes for Far-Infrared Astronomy
1977I would like to present some of the background and current activity in balloon-borne infrared astronomy, to examine a number of astronomical objectives in terms of their technical requirements, to describe some of the unique characteristics of ballooning techniques, and to illustrate how the objectives and techniques are mated with some specific ...

A scanning Fabry-Perot interferometer for far-infrared balloon astronomy
Infrared Physics, 1978Abstract Design and performance details of a scanning Fabry-Perot interferometer developed for far-infrared balloon astronomy are presented. Scanning is achieved mechanically by a parallel spring arrangement and plate spacing is measured by capacitance micrometry.

Far-infrared / submillimeter astronomy: Recent achievements and future possibilities
2014 39th International Conference on Infrared, Millimeter, and Terahertz waves (IRMMW-THz), 2014We discuss some recent astronomical results from the Herschel Space Observatory, and indicate future directions for astronomy and astrophysics enabled by submillimeter/far-infrared observations. A huge amount remains to be done, but it will require improved ground-based, suborbital, and space facilities.

A 102-cm Balloon-Borne Telescope for Far-Infrared Astronomy
Optical Engineering, 1977The Center for Astrophysics-University of Arizona balloon-borne, inertially-guided, 102 cm telescope was designed to perform photometry and high resolution mapping of far-infrared (40-250 micron) celestial sources. To date the telescope has now been flown and successfully recovered a total of ten times.

A discussion on infared astronomy - A far infrared sky survey
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1969A balloon-borne instrument for making far infrared sky surveys with 2° angular resolution is described. In two initial flights at a wavelength of 320 μm approximately half of the celestial sphere including most of the northern milky way was surveyed. The thermal emission of the moon was alone detected. The upper limit to the flux from other sources was
