EB-CCD
The EB-CCD is an entirely new type of high-sensitivity imaging device that employs the
"Electron Bombardment (EB)" effect. This effect intensifies images by accelerating an
electron image photoelectrically converted to strike the CCD while applying a high voltage.
The EB-CCD has a simple structure and theoretically has no deterioration in the S/N ratio
that usually occurs due to gain fluctuations. This means you get highly sensitive image
acquisition along with a high S/N ratio.
Two types of EB-CCD are available depending on the readout method. One is the N7640
designed to operate at the TV scan rate. The other is the N7220 for slow scan readout. The
EB-CCD is ideal for high-sensitivity video cameras in low-light-level applications where the
sensitivity of ordinary CCD cameras is too low.
The N7220 slow scan type can detect images down to single-photon light levels.

EB-CCD Camera C8080
The C8080 is an EB-CCD camera incorporating a TV scan type EB-CCD (N7640). The
C8080 is designed for simple use and functions, yet capable of imaging at very low light
levels. Hamamatsu also provides the C8081 power supply ideal for use with the C8080 EB-
CCD camera.
