The framing streak camera C4187 is able to analyze
ultra-fast optical phenomena in both framing and streak
modes through the interchangeable plug-in units. In
addition, a wide variety of peripheral devices allow you
to configure your own system for your specific applica-
tion.

The HPD-TA is a high-performance digital data acquisition and control system specifically de-
signed to read out images from the C4187 framing or streak camera’s phosphor screen.
The entire system is controlled through a powerful but user-friendly software application that
runs on a Microsoft Windows platform.
* A read out system based on the
® computer is also available. Please consult with our
sales office for more details.
High framing speed up to 3 million frames/sec., Short exposure time of 50 ns (fram-
ing mode) and Temporal resolution of 10 ps (streak mode)!
The Hamamatsu C4187 is a framing streak camera specially
designed for the observation and analysis of ultra-fast optical
phenomena. The interchangeable plug-in units give easy ac-
cess to two types of imaging operations: Framing and Streak.
In framing mode, the C4187 performs continuous imaging up to
8 frames at a framing rate up to 3 million frames/sec. and a
minimum exposure time of 50 ns. In addition, in streak mode, the
C4187 measures ultra-fast optical phenomena of 10 ps temporal
resolution and provides time, light intensity, and position (or
wavelength) information simultaneously. Employing a designed
ultra-fast imaging tube, the C4187 makes it possible to observe
and analyze ultra-fast optical phenomena at low light levels
previously impossible.
The C4187 can be further enhanced by use of a real-time
readout system, which is composed of a high-sensitivity video
camera, a data analyzer and other peripheral equipment which
can analyze image data of optical phenomena in real-time.
