Hamamatsu EB-CCD cameras use an innovative high gain sensor
that puts advanced technology to work to obtain high gain images
in very low light. This technology involves a special vacuum
chamber in which electrons generated at the photocathode are
accelerated by a high potential into a newly developed, back
thinned, back illunimated CCD. This direct bombardment of the
CCD by accelerated electrons provides high gain, high resolution
images, with none of the problems associated with Micro Channel
Plates which are used in other devices. The sensor in the EB-CCD
is driven by low noise circuits and features MPP (Multi Pin Phase)
technology to achieve good S/N ratios at high gain conditions and
a long service life.
Two different implementations of this technology are available. We
offer a selection between a video rate camera with both analog and
10 bit digital output at 30 fps.
