TRENTON, N.J., July 31, 2012 — Princeton Instruments has launched its ProEM+ series professional-grade electron-multiplying CCD (EMCCD) cameras for scientific imaging and spectroscopy applications. The next-generation cameras deliver the sensitivity, temporal resolution and quantitative stability required for very low light applications. They are available in four pixel formats: 512 × 512 and 1024 × 1024 for imaging, and 1600 × 200 and 1600 × 400 for spectroscopy. They provide ~95% peak quantum efficiency and single-photon sensitivity via built-in electron-multiplying gain functionality. The company also is releasing eXcelon3, an exclusive EMCCD technology that offers a broader sensitivity range and reduced etaloning. To afford researchers ease of use, all ProEM+ cameras are fully supported by proprietary LightField 64-bit image acquisition software. A new high-speed operation mode allows the cameras to run at >10,000 fps with reduced region of interest and binning. They also can be operated in kinetics mode for microsecond resolution. Features include low read noise, detector cooling to below −90 °C, an all-metal sealed design backed by a permanent-vacuum guarantee, OptiCAL for precise electron-multiplying gain calibration using a built-in stable light source, and a Gigabit Ethernet interface that ensures fast data throughput. The availability of 100-kHz “non-EM mode” operation renders the cameras suitable for use in steady-state applications with read noise as low as 2 e– rms.
