Research involving spectroscopic measurements is cutting-edge, whether it’s on the ultra-fast timescale, or detecting only a weak burst of photons. However, measurement accuracy is determined by the least accurate elements of the optical set-up. Coupling a streak camera, which measures ultrafast light (intensity, time and wavelength) with the HORIBA iHR320 imaging spectrometer, will dramatically improve those measurements.

Accordingly, HORIBA Scientific has developed a special version of its iHR320 imaging spectrometer to work in tandem with a streak camera to achieve the highest throughput possible.

HORIBA’s iHR320 spectrometer provides:

• High throughput, with an f/4.1 aperture, to ensure that the maximum amount of light is detected;
• Optimal optical design with on-axis rotation of the gratings on their front surfaces for constant and accurate focus on gratings;
• Single cast aluminum design to enhance rigidity when coupled to the streak camera and minimize stray light;
• Easy optical coupling with a focal plane approximately 29 mm outside the spectrometer box;
• Compatibility with industry-leading streak cameras, including the Hamamatsu Models C10910, C5680 (using A1926-01 input optics), and Streakscope Models C10627 and HC-4334 (no input optics). Hamamatsu software ensures you have complete control of your system.
• Coupling to an iHR550 with focal length of 550 mm possible.

HORIBA’s iHR320 spectrometer and a streak camera allows researchers to measure:

• Time-resolved fluorescence from nanoseconds down to a few picoseconds;
• Short-lived, weakly emitting samples;
• Photoluminescence of semiconductors such as GaAlAs;
• Quality-control of thin-film fabrication, for example, checking the uniformity of YBCO laser-ablation and deposition;
• Research and quality-control of lasers, such as the temporal characterization of laser pulses;
• Optical-communications research, e.g., chromatic and temporal dispersion in transmission through a single-mode optical fiber;
• Picosecond absorption spectroscopy;
• Picosecond Raman spectroscopy.
