Hamamatsu's gated ICCD camera C11370-10-1 is highly sensitivity camera capable of high speed gate operation (high speed shutter) to capture images of transient phenomena. Coupling a CCD camera to an image intensifier captures instantaneous high speed transient phenomena or instantaneous phenomena occurring with low-level light emission.

Features

  • High resolution
  • Super high speed gating to a minimum of 5 ns
  • Time-resolved imaging made simple by an auto-delay function
  • Simultaneous imaging on up to 4 channels (option)
  • Captures digital (12 bits) images
  • Photon counting for spectrum measurement at super high sensitivity

Measurement examples

Visualization of CF2 by LIF in a high frequency plasma

A plasma is generated by applying high frequency waves of 150 MHz to 6 mm in diameter alumina electrodes placed at a gap of 1 mm in a gas mixture (1 atm pressure) of He (99 %) and CF (1 %).

Principle

High-speed gated ICCD cameras are high-sensitivity CCD cameras that feature high-speed gate operation (high shutter speed). The image intensifier (or I.I.) coupled to a CCD camera enables high-speed gating along with high-sensitivity imaging. ICCD cameras can capture instantaneous action of high-speed phenomena as well as the faint light that occurs in instantaneous phenomena. They can also offer time-resolved imaging of reproducible phenomena by programming the gate delay timing.

Measurement technique examples

Time-resolved imaging using sampling method

When measureing repetitive phenomena, time-resolved imaging can be performed by shifting the gate delay timing automatically according to a user-programmed scheme.

c11370-10-1 measurement techniques


Eliminating background by high-speed gating

When the target phenomenon is buried in background light, the gating timing can be synchronized to match the target phenomenon to create clear images with high signal-to-noise ratio.

Capturing fluorescence (scattering) images by using a pulsed laser

This technique captures fluorescence images of samples of interest and its cross section by synchronizing the timing with a pulsed laser or excitation light source.

Measurements

Multi-channel measurements

Bidirectional simultaneous imaging

Capturing images simultaneously from 2 cameras oriented at different angles allows 3D analysis.

c11370-10-1 application example


Dual-wavelength simultaneous imaging

Light flux is split by a dichroic mirror and a band-pass filter is placed in each optical path to allow only light on the required wavelengths to pass through. Simultaneous imaging by 2 camera units allows capturing images at the same timing at different wavelengths. Also 2 image frames can be captured at extremely small intervals by removing the filters and delaying camera gate time on one camera unit versus the other camera.

Spectrum measurement

Spectrum measurement

Wavelength analysis of high-speed phenomena can be performed by combining with a polychromator. The polychromator can contain 3 gratings that allow versatile measurements by switching the spectral range and/or spectral resolution.

Multi-wavelength spectrum measurement*

Connecting a dedicated fiber (5-branch taps on input) to a polychromator allows high speed analysis at 5 different locations.

c11370-10-1 application example


High speed gated spectrum measurement

Changes in specific wavelength distributions can be acquired with time resolution in the nanosecond range by inserting a band-pass filter and acquiring images at incremental timing delays preprogrammed in the ICCD software.
