Universal Streak Camera C5680 Series
Measurements Ranging From X-Ray to Near Infrared With a Temporal Resolution of 2 ps
The streak camera is an ultra high-speed
detector which captures light emission
phenomena occurring in extremely short
time periods. Not only can the streak camera
measure intensity variations with superb
temporal resolution, but it can also be used
for simultaneous measurement of the spatial
(or spectral) distribution.
The C5680 Streak Camera Series is a
universal streak camera which incorporates
all of the specialized technology and
expertise HAMAMATSU has acquired in over
20 years of research. The streak tubes are
manufactured on a regular production
schedule at Hamamatsu to provide
consistency and reliability. Special requests
and custom designs are also available.

FEATURES
•
Temporal resolution of within 2 ps
A temporal resolution of 2 ps is achieved for both synchroscan
and single shot.
Several plug-in module, operating mode.
•
Accommodates a diverse range of experimental setups
•
from single light emitting phenomena to high-speed
repeated phenomena in the GHz.
•
Can be used in X-ray to near infrared fields
By selecting the appropriate streak tube (light sensor), the
C5680 can be used in a wide range of measurement applications, from X-rays to near infrared light.
Simultaneous measurement of light intensity on
•
temporal and spatial (wavelength) axes
Spectrograph can be placed in front of the streak camera, to
convert the spatial axis to a wavelength axis. This enables
changes in the light intensity to be measured over various
wavelength (time-resolved spectroscopy).
•
Ultra-high sensitivity (detection of single photons)
The streak tube converts light into electrons which are then
multiplied by an electron multiplier. This enables detection of
extremely faint light (at the single-photon level).
(See photon counting integration principle)
IEEE-488 (GP-IB) control
•
Computer control enables remote control and advanced
measurements to be performed out using very simple operation.
•
Diverse selection of peripheral equipment
A full lineup of peripheral devices is available, including
spectroscopes, optical trigger heads, and expansion units.
The operating principle of the streak camera

(where electrons
are swept in the
direction from top
to bottom)
MCP
(which multiplies
electrons)
Phosphor screen
(electrons → light)
The intensity of the incident light
can be read from the brightness
of the phosphor screen, and the
time and space from the position
of the phosphor screen.

OPERATING PRINCIPLE
The light pulse to be measured is projected onto the slit and is
focused by the lens into an optical image on the photocathode
of the streak tube. Changing the temporal and spatial offset
slightly each time, four light pulses, each with a different light
itensity, are introduced through the slit and conducted to the
photocathode.
Here, the photons are converted into a number of electrons
proportional to the intensity of the incident light. The four light
pulses are converted sequentially to electrons which are then
accelerated and conducted towards the photocathode.
As the group of electrons created from the four light pulses
passes between a pair of sweep electrodes, a high voltage is
applied (see above), resulting in a high-speed sweep (the electrons are swept in the direction from top to bottom). The electrons are deflected at different times, and at slightly different
angles in the perpendicular direction, and are then conducted
to the MCP (micro-channel plate).
As the electrons pass the MCP, they are multiplied several
thousands of times and are then bombarded against the phosphorscreen, where they are converted back into light.
The fluorescence image corresponding to the first incident
light pulse is positioned at the top of the phosphor screen, followedby the others, with images proceeding in descending order; inother words, the axis in the perpendicular direction on
the phosphor screen serves as the temporal axis. The brightnesses ofthe various fluorescence images are proportional to
theintensities of the corresponding incident light pulses. The
positions in the horizontal direction on the phosphor screen
correspond to the positions of the incident light in the horizontal direction.
THE PRINCIPLE OF PHOTON COUNTING INTEGRATION
Photoelectrons given off from the photocathode of the streak
tube are multiplied at a high integration rate by the MCP, and
one photoelectron is counted as one intensity point on the
phosphor screen. A threshold value is then used with this photoelectron image to clearly separate out noise.

(wavelength)
Positions in the photoelectron image which are above the
threshold value are detected and are integrated in the memory,
enabling noise to be eliminated completely. This makes it possible to achieve data measurements with a high dynamic range
and high S/N.

adjust the delay times of trigger signals. In addition, the amount
by which trigger signals are delayed is adjusted automatically,
while monitoring the sweep signal, enabling stable acquisition of
streak images over a long period of time.
This outputs an output signal of 100 MHz synchronized to the
