The objective of this study was to produce semiconductor films with values of E sub g and omega sub p(the 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.
