What is an EX-View CCD camera?
“EX-View” is a sensitivity-enhancement technology developed by SONY to improve light sensitivity of its CCD by a factor of two for visible light and a factor of four for near-infrared wavelengths.”
EX-View is a proprietary SONY technology in which the P/N junction of each photodiode in the CCD matrix is specially fabricated to have much better photon-to-electron conversion efficiency. In addition, each photodiode (representing one pixel in an image) has a microscopic lens fabricated over it to better capture and focus light onto the active semiconductor junction. This results in an improvement in light sensitivity of 2 times for visible light and 4 times for near-infrared (800 ~ 900 nm) compared to the conventional CCD versions offered by SONY. The lux rating of the EX-View CCD is two times better than the premium SONY “Super HAD” CCD for both visible and near-infrared wavelengths.
