Q: What is EX-View CCD camera.
A: "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.
EXview HAD CCD is a CCD that drastically
improves light efficiency by including near infrared
light region as a basic structure of HAD
(Hole-Accumulation Diode) sensor.
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.
