As polymeric filters are becoming more common, the mechanical and thermal limitations of the materials are often
overlooked, with designers focusing solely on the optical and spectral characteristics. This paper addresses the
environmental and optical characteristics of various types of polymeric materials. The materials are qualified and
quantified in relation to Ground, Air and Sea specification standards.
As the battlefield becomes "digitized", all arms of the military are deploying COTS displays in the form of
Portable Notebooks, Kneeboards, GPS and PDA's in ever greater numbers. Many of these COTS
equipments and associated displays use full color LCD's and resistive touch panels as the operator-interface.
These displays are a challenge to those who must modify the COTS equipment for NVG
compatibility. Traditional NVG filter options have relatively poor color rendering and are too thick or rigid to
interface with touch panels. In addition, many of these displays do not have sufficient dimming capabilities to
allow covert night-time operations and do not have sufficient luminance for daytime operations. Polymeric
materials recently developed by Wamco have been specifically designed for applications where traditional
NVG filters have failed. These applications will be discussed and quantified in terms of NVG Compatibility,
Color Rendering, Luminance Contrast and Daytime Readability, Touch Screen Sensitivity and Environmental
