NOTE:
a The light source is a tungsten filament lamp operated at a distribution temperature of 2856K. Supply voltage is 800 volts between the photocathode and all other electrodes (MCP-In, MCP-Out, Phosphor Screen) connected together as anode. b The luminous gain has relation to the screen luminance Lo (cd/m2) and the illuminance Ei (lx) incident on the photocathode, and expressed by: Luminous Gain = · Lo Ei
c The ratio of the phosphor screen radiant emittance in watts per square meter (W/m2) to the irradiance (W/cm2) on the photocathode. The supply voltages are the same as b. d The value at the wavelength of peak response. e The inherent background noise of an image intensifier is normally specified as the input illuminance (or irradiance) required to produce a luminous emittance from the phosphor screen, equal to that obtained when the input illuminance is zero. This indicates the lower limit of detectable illuminance of an image intensifier. f The measure of the ability to detect while and black stripes in an image formed at the photocathode, in terms of line pairs (Lp) (one black and one white stripe) per millimeter. This is the value at an MTF (Modulation Transfer Function) of 5%. g 1 lm/m2 =0.0929 ft-L 1 lx =0.0929 ft-c 1 lm/m2/lx =1 ft-L/ft-c
The supply voltages are as follows. Photocathode and MCP-In ..... 800 Vdc MCP-In and MCP-Out (1 stage MCP) .... 900 Vdc (2 stage MCP) .... 1800 Vdc (3 stage MCP) .... 2700 Vdc MCP-Out and Phosphor Screen ..... 6000 Vdc
