The ratio of the phosphor screen radiant emittance in watts per square
meter (W/m

) to the irradiance (W/cm

) 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%.

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/m
2
) and
the illuminance Ei (lx) incident on the photocathode, and expressed by:
Luminous Gain =

The supply voltages are as follows.
Photocathode and MCP-In .............. 800 Vdc

(1 stage MCP) .... 900 Vdc
(2 stage MCP) .... 1800 Vdc
(3 stage MCP) .... 2700 Vdc
