NV-2500

NV-2500 brochure

Designed to test night vision monocular or binocular goggles, the NV-2500 system provides automated testing of all standard NVD operational parameters with unparalleled accuracy and operator ease of use. Using the system via a built-in touchscreen, users can view test results in real time without straining eyes to look through the goggles. EOI's unique system architecture allows for best-in-class repeatability (in-system and system to system) and many of the tests are automated thus removing judgment calls and alignment errors often encountered by user variability, while also improving test time. For backward compatibility, operator performed (manual) versions of the tests are also selectable. Users may download or print test reports via USB or optimized printer with English or Spanish language operation selectable by the user.

Configuration

The NV-2500s unique architecture includes all the necessary accessories required for operation with all standard NVD tests at no extra charge. Through the touchscreen, operator manuals and contextual help are provided – no need to fumble through paper manuals. Additionally, 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

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. 

NV2020 no backgrnd

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.
