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.

High Performance NVIS Filter for Harsh Environment
Cevians designs its optical products to meet the most rigorous environmental requirements. This paper provides an in-depth review of the methods and procedures utilized in the design and qualification of Cevians NVIS products for LCDs. Typical NVIS filter constructions are either laminated coated glasses, featured in Cevians' BlackBackground design, or coated monolithic glass, used in Cevians' UltraNVIS design. The quality of lamination plays a critical role in the overall performance, with the characteristics of the thin film deposition being of utmost importance. Parameters such as substrate preparation, material selection, and deposition conditions significantly impact the environmental characteristics of the coated elements. Additionally, this paper reports on and compares the environmental performance of both Cevians UltraNVIS and BlackBackground designs, as used in some of the world's most advanced NVIS-compatible display applications, including fifth-generation fighter jets.
