BASIC INFORMATION:
The ITS-P measuring station is a test system that enable testing reactions of image intensifier tubes to light flux at
different intensity levels. The ITS-P station illuminates tube photocathode with precisely controlled light flux
and measures output intensity at the tube screen. The station enables measurement of all important photometric
parameters like luminance gain, saturation level (max output luminance), EBI (equivalent background
illuminance), photocathode luminous sensitivity, photocathode radiometric sensitivity, operational stability and
tube current consumption. ITS-P can be also optionally used for measurement of temporal parameters like rise
time, decay time, phosphor decay time (luminance persistence).
The station is built as a modern compact stand alone test station optimised for testing II tubes (not an archaic
collection of different laboratory modules to be assembled by the user on a table). Practically all image
intensifier tubes offered on the market can be tested (different sizes of photocathode: 16mm, 18 mm, 25 mm (and
optionally 300mm or 400mm); different generations: 2, 2+, 3, 3+; potted tubes or bare tubes). The test procedures
used by the ITS-P station are based on recommendations of the MIL series standards.
WHY TO TEST
 Photocathode luminous sensitivity and photocathode radiometric sensitivity –parameters that determine
potential tube sensitivity,
 Luminance Gain – how many times brightness of the image of the observed scenery on the II tube screen
is higher than brightness of the original scenery,
 Saturation Level (Maximal Output Luminance)– maximal screen brightness when tube is saturated,
 EBI – input illumination equivalent to screen brightness when tube is not illuminated,
 Operational stability - temporal variation of screen brightness when input illumination is stable.

ITS-P
Test station for measurement of photometric parameters of II tubes
FEATURES:
 Enables to carry out the following tests:
o Luminance gain, saturation level, EBI, operational stability, current consumption of potted
tubes
o Luminance gain, saturation level, EBI, luminous sensitivity, radiometric sensitivity of bare II
tubes
 Continuous regulation of illuminance that enable thousands of different illuminance levels (typical test
systems have step illuminance regulation and enable only no more than half a dozen of illuminance
levels)
 HVP1 power supply needed for photocathode tests is included. Optionally HVP14 power supply to run
complete care tube can be delivered.
 Different versions of ITS-P station of different measurement capabilities can be delivered.
