The C7876 series X-ray image intensifier (X-ray I. I.) camera
units are ideal for non-destructive inspection of light-element
materials and radiation imaging at low-energy X-ray levels. The
C7876 remarkably improves X-ray transmittance at low-energy
X-ray levels because a beryllium (Be) window is used instead of
the aluminum (Al) window currently used in most X-ray image
intensifiers.
The result is a clear, distinct image taken in real time even at
low-energy X-ray levels down to several keV. For example, the
internal structure of thin resin or aluminum objects, which have
been difficult to visualize, now can be clearly observed with high
contrast.

FEATURES
BERYLLIUM WINDOW EFFECTS
The C7876 series uses an X-ray image intensifier having a beryllium (Be) window instead of the aluminum (Al) window
commonly used in most X-ray image intensifiers. This has brought a significant improvement in X-ray transmittance at low-
energy X-ray levels, making it possible to capture a clear, high contrast X-ray image of objects which up until now have
been difficult to capture with good contrast.

SPECIFICATIONS
BERYLLIUM WINDOW SAFETY PRECAUTIONS
Beryllium (Be) is used for the window of this product. Beryllium is solid under normal conditions and not
harmful as long as it stays unchanged in quality. However, if beryllium is mechanically or chemically pro-
cessed and inhaled as fumes or in powder form, it may be extremely harmful. To prevent beryllium from
entering your body through a cut, breathing, eating or drinking, NEVER TOUCH THE BERYLLIUM WINDOW
WITH BARE HANDS. Should you touch the beryllium widow or debris when broken, immediately wash your
hands or other parts of the body that came in contact with the beryllium.
Beryllium is designated as a chemical substance that must be handled in accordance with authorized
disposal methods. If this product is broken or has reached the end of its service life, please contact our sales
office to ship it back to us and we will take the proper means to dispose of it.

RELATED PRODUCTS
130kV Microfocus X-Ray Source
The Hamamatsu microfocus X-ray source uses an X-ray tube with an extremely
small focal spot of 10 microns in diameter. This gives a sharp, clear image even at
magnified image. When used with the C7876 series X-ray I. I. camera unit, high-
quality X-ray images can be taken in fine detail even under high magnification.
Besides the 130kV model, Hamamatsu offers various models of microfocus X-ray
sources, including 80kV, 100kV and 150kV models.
X-ray Image Intensifier Camera Unit (3"/1.8" Dual Mode)
C7716, C7716-10
The C7716 series X-ray image intensifier (I. I.) camera unit now offers greatly
improved X-ray detection efficiency even at low energy levels. This improvement
stems primarily from a built-in X-ray image intensifier having an extremely thin
aluminum input window. Its thickness is only 0.3mm or less, virtually at the limit of
present technology providing excellent X-ray transmittance and low scattering.
The results are sharp, clear, high-quality images taken at low energy X-ray levels
down to several keV which penetrate plastic (PET) materials.
X-ray Image Intensifier Gate Unit C7077
The C7077 X-ray image intensifier gate unit consists of a gateable 4-inch X-ray
image intensifier (X-ray I. I.) with a relay lens and a gate power supply. Since the X-
ray I. I. itself has a gating function, still X-ray images of a high-speed moving object
can be taken by inputting an external trigger signal while using a normal X-ray
source. This means there is no need for a pulsed X-ray source. Gating can be
performed by a TTL level trigger pulse, allowing easy gate control.
FOS (Fiber optic plate coated with X-ray scintillator)
The FOS is an optical device for X-ray imaging, fabricated by coating an X-ray
scintillator material over a fiber optic plate consisting of tens of million glass fibers
of several micrometers each in diameter. The FOS provides higher sensitivity and
resolution than currently used sensitized paper films and also allows real-time
digital radiography when directly coupled to a CCD. The fiber optic plate used in the
FOS has excellent X-ray absorption characteristics, so that X-rays which penetrate
the X-ray scintillator and directly enter the CCD are minimized to less than 1%. This
protects the CCD from "deterioration" and "noise increase" caused by X-ray
irradiation, assuring a long service life and maintaining high image quality.
