TRENTON, N.J., April 16, 2013 — Princeton Instruments has launched emICCD technology for its PI-MAX4 camera platform, combining the advantages of intensifiers and EMCCDs to provide single-photon sensitivity and quantitative performance for scientific imaging and spectroscopy applications.
The series features <500-ps gating, very high repetition rates, radio-frequency modulation and complete control via the company’s LightField 64-bit data acquisition software platform, which remembers each user’s hardware and software configurations and tailors its own features accordingly, displaying all relevant tools via an intuitive graphical user interface.
In an emICCD camera, either a back- or front-illuminated EMCCD is fiber optically bonded to an intensifier with an S20/S25, GaAs or GaAsP photocathode for light throughput. Using both the intensifier and the EMCCD gains, the detector provides a larger dynamic range than that of an intensifier alone. This wider linear range is useful for quantitative measurements in comparing bright and dark scenes within a single image.
The same camera can be operated at the highest system gain to detect single photons, overcoming the excess noise limitations of typical gain systems. New emICCD cameras also feature a built-in, fully calibrated, high-precision timing generator with 10-ps time resolution for external synchronization. These high-frame-rate (>30 fps) cameras can be operated remotely via a Gigabit Ethernet data interface.
