Monochromatic light sources in testing image intensifier tubes

Krzysztof Chrzanowski, Tomasz Raźniewski, Bartłomiej Radzik


Military standards and literature sources recommend use of polychromatic light source of 2856K color temperature in testing image intensifier tubes. Tungsten halogen bulbs are standard sources of radiation used in commercially available test stations. However, there are two main disadvantages of tungsten bulbs: short life time and temporal changes of both light power and light spectrum. Application of monochromatic semiconductor sources in testing of image intensifiers as possible alternative of halogen bulbs is analyzed in this paper. It is shown that, if calibrated properly, monochromatic semiconductor sources can be used in stations for testing image intensifier tubes.
