NV-2020 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.
