Image Intensified Lightweight Lens Development
Agency / Branch:
DOD / SOCOM
In recent engagements, the military has employed unconventional methods to gain a tactical advantage. One of these methods is increased night patrols and night combat operations using night vision goggles. Even though the capabilities of these devices have increased, they are still large and heavy, which reduces individual mobility and increases soldier fatigue. The classical approach at reducing system weight is to replace the glass lenses with plastic components. However, this has had limited success because of the large index difference between glass and plastic and the large focus shift with temperature from plastic components. We propose a new approach where the requirements for the application match the performance of the light-weight, all plastic lens, NVG system. We will survey and analyze existing NVG systems and select a system whose performance and layout allow the glass lenses to be replaced with plastic lenses. We will also investigate different mechanical housing configurations using dissimilar metals and composite materials to compensate the focus shift from changes in temperature. By this approach, we will develop new processes that will further develop the capabilities of light weight night vision optics.
