Imaging Charge Couple Device:

Time domain measurements have become increasingly important in many materials and spectroscopic analysis. Time gated measurements, which capture small time intervals but with full spectral information, are one key technique. HORIBA Jobin Yvon has been very active in time resolved measurements and our Intensified Charge Couple Device (ICCD) system is an ideal choice for time gated spectral applications from nanoseconds to seconds in the UV/Vis regions.

Technical Specifications:

The HORIBA Jobin Yvon i-Spectrum Two ICCD detectors provide a fully integrated instrument for time resolved measurements. Our detectors offer superior performance in gating frequency, speed, sensitivity, dynamic range, readout noise and spectral acquisition rates – all in a compact, rugged and economical package. The i-Spectrum Two family of Intensified CCD detectors is designed with scientific grade thermoelectrically cooled CCDs and a grade (1) gateable image intensifier. As its name suggests, the image intensifier amplifies, by a factor up to 10
4 , the intensity of the incident light upon it which is then detected by a CCD sensor. The image intensifier can be switched on and off in a few nanoseconds, allowing it to act as an ultra fast electronic shutter. This controls the exact timing of the signal incident onto the CCD sensor, making these detectors ideal for nanosecond scale time resolved measurements of transient phenomena. The ultra electronic gating capabilities of the i-Spectrum Two ICCDs also makes them perfect for measurements requiring the isolation of weak signals of interest from a strong noise background. In applications such as pulsed Raman spectroscopy and plasma analysis by laser-induced fluorescence, the detector can be precisely synchronized to collect signal for a few nanoseconds when laser is on. This allows the detector to gate out any noise background or fluorescence when the laser is off.
