Night Vision Test Sets

Designed for testing night vision monocular or binocular systems, the NV-2500 system provides automated testing of all standard NVD tests with unparalleled accuracy and operator ease of use. Users operate the system with a built-in touchscreen where they can view test results in real time video without eye strain looking through binoculars. Our unique system architecture allows for best-in-class repeatability (in-system and system to system). Tests are automated thus removing many judgment calls and alignment errors often encountered by user variability, while also improving test time. Operator manual versions of the tests are also selectable for backward compatibility. Users may download or print test reports via USB or optimized printer. English or Spanish language operation is selectable by the user.

Configuration:

The NV-2500's unique architecture includes all the necessary accessories required for operation of all standard NVD tests at no extra charge. Operator manuals and contextual help are provided on-board via the touchscreen – no need to fumble through paper manuals. Users may purchase an auxiliary printer to connect to the system for report printing or simply download reports to your preferred device via the USB slot.

NV-2020 brochure

NV-2020 night vision optical alignment system presents a resolution pattern at correct infinity focus to both Night Vision Device (NVD) channels at once. It is a compact and portable reference device that allows the user to accurately adjust goggles just before a mission providing for a proper and quick adjustment of all goggle parameters.

Configuration

It is paramount that the user adjusts the goggle mount for proper tilt and eye relief, sets up the goggle IPD (Interpupillary Distance) spacing, and adjusts the focus of each eyepiece and objective lens assembly during pre-mission NVD adjustment.

The NV-2020 optical alignment system allows proper adjustment of all goggle parameters prior to a mission and provides an accurate target at infinity focus. Along with a large folded-mirror collimator, the NV-2020 projects multi-bar patterns of known resolution at light levels that are appropriate for both "high-light" and "low-light" NVD resolution. NV-2020 may be used with any goggle type and the eight-step grayscale covers a range of 2 1/2 decades and checks the NVD over a variety of light levels.
