The objective of this study was to produce semiconductor films with values of E sub g and omega sub pthe plasma frequency such that the films would have a luminous transmission of 75 and an optical density of at least three throughout the wavelength band 1.0 to 1000 micrometers. Development of such broad band IR filters involved 1 a study of the transmission characteristics of candidate semiconducting films of indium tin oxide deposited on glass and specified optical-quality plastic substrates, 2 examination of the problems of film-base material compatibility, if any incompatibility exists, 3 examination of techniques for increasing the near-infrared rejection of the film while maintaining high luminous transmission, and 4 construction and testing of semiconductor coated plastic and glass eye protective devices.
