NVC150 Night Vision Compatibility Testing

  • NVC150 Night Vision compatibility characterisation
  • NVC150 System Set-up
  • NVC150 Telescope view
  • NVC150 System Set-up

Featuring two configurations, as a spectroradiometer, the NVC150 permits accurate assessment of interior lighting (MIL STD 3009) and exterior lighting (SAE ARP5825, STANAG 1445 etc) whilst as a spectrophotometer, is utilised in the detailed evaluation of NVIS filter transmission.

Across all applications, the superlative performance of the NVC150, including excellent stray light rejection and unparalleled sensitivity, delivers accurate NVIS compatibility characterisation and ultimate measurement confidence across the life time of the system.

Core benefits


  • Double monochromator for superlative stray light performance
