EB-CCD
TV SCAN RATE TYPE : N7640
SLOW SCAN TYPE : N7220
For Low-Light-Level Imaging with high S/N ratio
The EB-CCD is an absolutely new high-sensitivity imaging
device that employs the “Electron Bombardment (EB)” effect for
image intensification. The EB-CCD basically consists of a
photocathode and a CCD chip arranged in parallel in a vacuum
tube. An optical image is converted at the photocathode into an
electron image, which is then accelerated and directly bom-
bards the CCD surface to produce electron multiplication. Even
a low-light-level image can be brought into view with a high S/N
ratio.
Two types of EB-CCD are available depending on the readout
method: the N7640 designed to operate at the TV scan rate
and the N7220 for slow scan readout. Both types are compact
and simple in structure, and deliver high sensitivity yet ensure
high S/N ratio. The EB-CCD will open up new applications as
the next generation of low-light-level imaging devices.
