ANV-120 NVD
The ANV-120 Night Vision Device (NVD) Gain Bench consists of a 12-inch integrating sphere with a special low-light-level lamp source and variable Aperture, an amplified detector probe with screw-on adapters that fits over the eyepiece of the goggle or night scope under test, and an electronics console which provides power and display functions for the set. The system is self-contained for measurement of goggle gain in terms of output luminance per unit of input luminance. The test set digital displays indicate source lamp current, source brightness in footlamberts, output screen luminance in footlamberts, goggle voltage and current demand, and system gain.

The lamp source housing has a series of fixed and variable apertures, which attenuate the light entering the sphere from a 10-watt quartz-halogen lamp. The amount of light projected into the sphere is controlled by a log taper aperture driven by a micrometer.

Nearly all NVD types can be tested through the use of custom adapters that are sold separately. The ANV-120 is a laboratory grade instrument with complete system calibration and NIST traceability.
