Abstract
Detection of 253.7 nm radiation in the solar blind UV spectrum is enhanced y using an energy wavelength shifter with a photomultiplier tube which senses fluorescent emissions. A ruby block wavelength shifter has a coating that passes energy including the 253.7 nm radiation and a layer that passes radiation within a bandwidth including the fluorescent emissions. The ruby block absorbs the energy of the 253.7 nm radiation and produces fluorescent emission that passes through the layer. The photomultiplier tube is sensitive to the fluorescent wavelengths to aid in detection. The relatively large coated area provides a wide aperture, wide field of view detection of the 253.7 nm radiation.
