NVIS Filtering Components

Scroll down

Cevians custom developed a range of NVIS filtering components, establishing the industry standard for compliance to MIL-STD-85762. Components are made of monolithic glass, polymers, or composites. Material absorption and chromaticity are tailored to optimize light source efficiencies for integration in MIL-P-7788 illuminated panels and keyboards.

  • Since 1984

    In production since 1984, components have been integrated into any NVIS compatible aircraft in the free world.

  • Incadescent lamps to LED

    Cevians has a broad array of standard components to filter sub-miniature and miniature incandescent light bulbs as well as a number of surfaces mount white LEDs. The components are compatible with multiple types of adhesive for full material compatibility when installed in MIL-P-5425 Acrylic panels. They are highly heat resistant and outlast all light source life. Most standard sizes are available from inventory.
