15 Feb NVIS Compliance vs. Compatibility
MIL-STD-3009 and MIL-L-85762 are the defining standards for NVIS products. Jayco makes products that are compliant to these standards. These are complex technical standards with several provisions that make full compliance expensive to achieve.
Most aerospace and defense applications that require NVIS specify compliance, but there are instances where a compatible product may be acceptable.
Now, there is no argument about what “compliance” means; but “compatible” can mean different things to different people. In our view an NVIS compatible product is one that can successfully be used with night vision goggles (NVG) without appearing significantly different to the products around it.
In contrast to a spectoradiometer that can measure color, radiance, and luminance to the nth degree, the human eye is very forgiving and adaptable. Therefore slight variations in color, energy output, or brightness, may not be noticeable, even when amplified through NVG. So a product that doesn’t fully measure to the strict standards of MIL-STD-3009 or MIL-L-85762 may still be acceptable when viewed through NVG. We call this NVIS compatible.
Why is this important? In a word, COST!
NVIS compliant products require special design, materials, extensive testing, and light balancing to achieve compliance. It is very time consuming to go through the full process to achieve compliance and certify it. Whenever it is required, we do it; but for those not quite so critical applications, we have a more economical solution.
Jayco has developed a proprietary method to make HMIs that are very close to full compliance – that are NVIS compatible – at a fraction of the cost of fully compliant products. Our design and process reduces material costs and simplifies production and assembly; giving you a savings of 25~40% over compliant products. This represents hundreds of dollars of savings per part on something like a 10.4” display bezel!
We still test our compatible products – so we know how close to compliance they really are. They typically measure within 95~99% of compliance – a small difference that adds up to huge savings. So, whether you need a fully compliant product, or you would like to save 25~40% on your NVIS HMI needs, give us a call. We can help you either way.
