NV-2020
NV-2020 Night Vision Optical Alignment System
NVD QUICK Pre-Mission Check and Adjustment
The 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. The NV-2020 allows users to accurately adjust goggles just before a mission, thus providing users with a proper and quick adjustment of all goggle parameters.
Like HGH’s NV-2500 system, the NV-2020 provides unparalleled ease of use.

NV-2020 Configuration
It is paramount that users adjust goggle mounts for proper tilt and eye relief, set up the goggle IPD (Interpupillary Distance) spacing, as well as adjust the focus of each eyepiece and objective lens assembly during the pre-mission NVD adjustment.
The NV-2020 optical alignment system performs proper adjustment of all goggle parameters prior to a mission. It provides an accurate target at infinity focus. In addition to 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. Further, the 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.
