Newcon Optik NVS 14 manual Image Intensifier Tube Specifications, Main parameters

5. IMAGE INTENSIFIER TUBE SPECIFICATIONS

The Unit utilizes a small size inverting image intensifier with direct image transfer. The tube contains a microchannel plate, multi-alkaline metal S-25 (NC tube type) or GaAs (N3 tube type) photocathode, yellow-green screen and built-in electronic high voltage DC to DC converter. The input window is made of flat surface glass. The output window is a concave fibre optics element with 180° image rotation.

Both tube types are manufactured in two grades HD (High Definition) or XT (eXTreme performance).
