Night Vision/Thermal Imaging
Image enhancement works by collecting the tiny amounts of light, including the lower portion of the infrared light spectrum, that are present but may be imperceptible to our eyes and amplifying the light to the point that we can easily observe the image. Thermal imaging technology operates by capturing the upper portion of the infrared light spectrum, which is emitted as heat by objects instead of simply reflected as light. Hotter objects such as warm bodies emit more of this light than cooler objects like trees or buildings. Common applications include night vision goggles for military, law enforcement, navigation, surgical imaging.
JDSU provides a range of filters in the visible and near-infrared region with optical densities of > 6. The filters provide excellent light transmission/reflection levels, excellent spectral stability and coating uniformity, and durability.
