Near-Infrared Sensitized Photocathodes and Film Sensitivities for Typical Xenon-Lamp Radiation and Related Subjects

Author Institution: Solid State Physics Research Laboratory, Wright-Patterson Air Force Base, Ohio 45433Weighting or assessment factors of near-infrared photocathodes and Kodak 5424 film are determined for xenon-lamp illumination. These values are important for selecting detectors and determining the basic sensitivity for a given situation and instrumentation; for example, in medicine, when obtaining retinal pictures. Some other typical applications are also discussed. Charts showing the radiation from a xenon-arc lamp, with a 0.5 mm arc length and 800 watt input, and the typical efficiency values of photocathodes and film to xenon-lamp radiation are presented at spectral intervals of 20 nm for the range of 400 to 1100 nm, with and without Kodak Wratten filter 89b
