Abstract
A night vision device includes an image intensifier tube having a photocathode responsive to light in the wavelength range extending from about 1 .mu.m to about 2 .mu.m. The photocathode releases photoelectrons in response to photons of light in this wavelength range. A photomultiplier tube includes such a photocathode to provide an image in response to light of such a wavelength. A method of making such a photocathode is set out.
