Increased dark current over time in EXview sensors. It is known that radiation damage increases the dark
current of a CCD sensor. This is also true for radiation arising from natural sources, also known as background
radiation.
These sources include: (1) terrestrial radiation from naturally occurring radioactive isotopes in the soil; (2)
cosmic radiation originating in outer space; and (3) naturally occurring radioactive isotopes in the body.
The EXview series of CCD sensors have greatly improved responsivity, especially in the Near IR part of the
spectrum. This greatly improved performance comes at the price of accelerated degradation (increased
dark current) due to natural background radiation. This degradation effect is approximately 4 times as fast
as in standard sensors, such as Hyper HAD sensors. The degradation effect will manifest itself as in
increasing non-uniformity of pixels when viewed in the dark (white spots). This is a natural effect, and is
not eligible for warranty replacement/repair of the CCD camera.
