Framing Unit M4189

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 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.

High-speed Framing Rate Up To 3-million Frames/sec

SYSTEM CONFIGURATION

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

sales office for more details.

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.

respectively

q Continuously adjustable frame rate and exposure time

q Switchable number of frames up to 8 frames

q External synchronization

q Multi-exposure imaging

q Wide wavelength range: 200 nm to 850 nm

q Ultra-high sensitivity imaging

q Dedicated real-time readout system

OPERATING PRINCIPLE OF FRAME

RATE AND SHUTTER SPEED

MODE1: When inputting an external trigger pulse, continuous

N-frame images (N=1,2,4,8) are automatically performed with

constant exposure time Te and frame interval Ti.

MODE2: Whenever inputting external trigger pulses, each one

frame image is performed. The exposure time Te is constant.

Synchronous imaging with laser pulses are also possible.

MODE3: Imaging with exposure time and frame interval based

on trigger signal using a multipulse generator C4398 is per-

formed. The exposure time and frame interval can be set by a

multi-pulse generator C4398.
