NVIS Light Leak Filter Kit


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


  • Easy to use
  • Cost effective
  •  Identifies light leaks per DO-275


  • Easy to use
  • Durable
  • Ensures flight safety
