Abstract

Hollow glass guides are of interest for temperature and gas sensing devices, for JR surgery and industry, for spectroscopic and radiometric applications in the JR range from 2 to 20 pm. Institute for Roentgen Optics (IRO) is one of the world leaders in x-ray hollow glass optics production. These products are used for transmission and focusing x-rays in the range from 0.2 A (6OKeV) and up. Key technology features are: inner diameters ranging from 0. 1 micron up to several millimeters; length of capillaries ranging from several millimeters up to 1 .5 meter; assemblies of capillaries (lenses, collimators, anti scatter grids) ranging in sizes from 0.1 millimeters up to 200 millimeters. Soon it will be possible to cover the poly capillary channels with metals Ag and Ni. During the mid-1989 till the mid-1990's we were developing x-ray capillary guides and by initiative one of the authors tested them for IR-applications. We found the transmission losses ~4dB/m (SiO₂- based glass, inner diameter a=lmm) and 8dB/m (GeO₂- based glass, inner diameter a=O.7mm) at the wavelength 10.6 μm. In the report we consider single glass capillaries and bundles of capillaries for transmission, focusing, angular and spectral filtration of IR-radiation.
