Owning the night

We are the uncontested technology leader in night vision materials. In 1984 we led one of the most historical pivots in military history, developing the first filtering component for incandescent lamps. This enabled full night vision compatibility with existing military aircraft, giving our pilots unprecedented capabilities to dominate the night sky.

Not only did Cevians design and produce the first contrast-enhancing NVIS filters for CRT and LCDs but we assisted the US Navy in the definition of the MIL-L-85762 which has driven the entire industry benchmark.

In the ensuing decades, we continued to lead development such as BlackBackground™ technology that is now the ultimate requirement for night vision compatibility. Cevians can proudly and unequivocally claim to have its materials and technology on any flying night vision capable aircraft in the free world.

NVIS Products

  • Do you guarantee NVIS product compliance?

    Cevians’ NVIS products and materials are certified to MIL-STD-3009 testing requirements. All optical testing is performed internally with high-performance equipment traceable to the U.S. National Institute of Standard and Technology.

  • What is the difference between MIL-STD-85762A and MIL-STD-3009?

    For most requirements, the specifications are identical. MIL-STD-85762A continues to be used in large part due to the requirements and test method of high ambiance contrast which is not a part of MIL-STD-3009. MIL-STD-3009, however, includes new NVIS chromaticity definitions and requirements that are used in certain situations.

  • Does NVIS compliance mean products will meet BlackBackground™ compliance?

    No. The current radiance limitations in MIL-STD-3009 and MIL-L-85762A were defined at a time when display technologies were mostly emissive type (CRT and TFEL), with no energy in the black screen area, and when the number of displays was limited. In today’s cockpit environment with extended display surfaces using transmissive AMLCDs with NIR contribution in black screen area, the overall NIR contribution is increased in the cockpit and limits night vision goggle performance. BlackBackgroundTM is a more stringent NVIS radiance requirement. All BlackBackgroundTM compliant displays are NVIS compliant, however, compliance to MIL-STD-3009 might not be BlackBackgroundTM compliant.

  • What is the chromaticity specification for NVIS displays?

    The military standard specifies a maximum level of radiance in order to limit the impact on night vision goggles. Specific requirements will usually identify a particular chromaticity. With goggles having sensitivity at higher wavelength including in the red portion of the visible spectrum, the sharpness of the attenuation in the red wavelengths will allow higher red content and thus provide for a more vivid red.

  • Can I guarantee that my final product will be compliant with night vision requirements when using certified night vision materials and products?

    No. Unfortunately, while the material or components will perform to the level of compliance, the designer needs to consider several factors during product engineering. It is very common that NVIS components are integrated into a design where other materials in the assembly will fluoresce. The fluorescence phenomena follows a typical Stoke reaction where the lower wavelength energy emitted from a compliant NVIS light source is absorbed by other materials, generally plastics or paints. The chemical content of these materials will absorb that higher frequency energy and re-emit light at lower frequencies and higher wavelengths which can affect the radiance contribution.
