4G Image Intensifier Tubes can offer ultra-fast Auto-Gating, the smallest halo and unrivalled spectral range from ultraviolet to near infrared.

Gain the advantage in the darkest nights, in all terrain and applications with 4G standard, the latest technology in intensified night vision specifically designed to address the stringent requirements of end-users:

  • An Extended Bandwidth of photon collection to deliver a consistently high image quality in all environments (from below 400nm to above 1.000nm)
  • A FOM (figure of merit) above 1.800
  • A Resolution always superior to 64 lp/mm even in the most polluted light environments such as urban areas or when entering a building where the light is suddenly switched on
  • A Halo size never larger than 0.7mm around the brightest objects seen in the image to provide the highest details around the light sources
