    Abstract: An apparatus for radiometric measurement of thin fluid films includes a housing (1) enclosing means of radiation, a radiation guide, a reflector (4) and one or more detectors (5). The means of radiation is normally an IR radiator (2). The radiation guide is either a radiation tube (3) or a radiation cone (7). The reflector (4) is of the type non-imagining optics. If there is more than one detector (5) normally at least one detector is a reference detector.

    Abstract: Crime scene lighting devices are used in forensic criminology for illumination and investigation at crime scenes using fluorescence excitation. High radiation powers are required both for white light in the so-called general search and for the criminologically relevant UVA-blue-green range. Moreover, it should be possible for the crime scene investigator to use the forensic lighting device portably and independent from the public power supply. The present disclosure relates to a suitable crime scene light device with a mercury ultra high pressure lamp as the light source, a light guide and terminals for operating the lamp selectively with an accumulator or the public power supply system. A suitable carrier bag, a so-called lorgnette with various longpass filters and a cross-section converter for visualizing shoeprints form useful accessories of the forensic lighting device.

    Abstract: Portable battery-operated ambient air analyzer comprising an electrically-energized incandescent source of infra-red radiation producing a beam passing through an air sample to a sensor. The infra-red source is surrounded by an explosion-proof enclosure to prevent an explosion internally of the enclosure being propagated out to the atmosphere. The incandescent source is a self-supporting filamentary coil having no interior core or mandrel. The coil is formed of a metal composition including aluminum, chromium and iron, operated at a temperature of less than 1000.degree. C.
