The Advanced Components Evaluation System at NOSC is a computer controlled test system for collecting and processing radiation effects data from multiplexed infrared detector arrays. The system is designed to support testing at a variety of radiation sources such as neutron, gamma, and xrays.
A lens that images at a distance of 10 mm cannot be properly positioned on an IR camera that needs a minimum distance of 30 mm. Lenses are commonly identified by their focal length, sometimes referred to as effective focal length. As the focal length increases, the field of view for that lens will be narrower.
