Abstract: A night vision device (10) includes an image intensifier tube (14) which includes a photocathode (22) responsive both to white light and to infrared light to release photoelectrons. The photocathode (22) is particularly sensitive to infrared light at the 980 nm wavelength, and has desirable spectral response characteristics.
