NVIS Light Leak Filter Kit
Hoffman’s NVG-105 Light Leak Filter Kit

OVERVIEW
Hoffman’s NVG-105 Light Leak Filter Kit is an easy solution for converting your existing ANVIS-6, ANVIS-9 or F-4949 Night Vision Goggles into an Inspection Scope for light leak checks.
In the event of a failure to pass the NVG Conformity Test, Inspection Scopes are a required tool for identifying light leaks per DO-275. The NVG-105 utilizes a precise filter that allows the user to identify non-compliant devices that would decrease night vision goggle visual acuity. The kit is an easy to use, cost-effective way to evaluate a crew station lighting to ensure flight safety.
Ideal scenarios for NVG-105 use include:
- Preflight inspection
- Recurring inspections
- Evaluation of newly installed instruments
- Evaluation after instruments have been serviced and/or repaired
- Local protocol for aircraft inspection
