Night vision compatibility testing

NVC150 from Bentham

The NVC150 is an essential tool in the evaluation and development of night vision enabled products, ranging from goggles through to displays.

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.

Features

Double monochromator for superlative stray light performance
Thermoelectrically cooled photomultiplier detector (S20 photocathode)
Optional spectroradiometer and spectrophotometer modes
Range of telescope input optics
Reports colourimetric parameters, luminance, NR_a and NR_b

Further information

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.
