Abstract

The response of lead sulfide photoconductors to a uniform field of monochromatic radiation, which was varied in wavelength from 0.4 to 3.0 μ and in angle of incidence from 0° to 80°, has been experimentally investigated and compared with derived response curves. Deviations from the ideal cosine response of up to 20% at 70° incidence were effected mainly by reflection losses from the detecting surface and by characteristics of the substrate. The results suggest that the grain size of the polycrystalline lead sulfide may considerably influence the reflection losses. Methods of correcting the observed deviations are discussed.
