Princeton Instruments has launched its ProEM+ series of EMCCD cameras for scientific imaging and spectroscopy applications. These cameras deliver the sensitivity, temporal resolution, and quantitative stability required for very low light applications.
ProEM+ cameras are available in four different pixel formats: 512 x 512 or 1,024 x 1,024 for imaging, and 1,600 x 200 or 1,600 x 400 for spectroscopy. The cameras provide ~95 per cent peak quantum efficiency as well as single-photon sensitivity via built-in EM gain functionality.
Concurrent with the release of ProEM+ cameras, Princeton Instruments has also released eXcelon3, an EMCCD technology that offers a broader sensitivity range along with reduced etaloning for excellent performance.
All ProEM+ cameras are fully supported by Princeton Instruments’ LightField 64-bit image acquisition software. Additionally, a new high-speed operation mode allows the cameras to run at more than 10,000fps with reduced ROI and binning. ProEM+ cameras can also be operated in kinetics mode for microsecond time resolution.
New ProEM+ cameras offer several novel features, such as OptiCAL for precise EM gain calibration using a built-in stable light source, a low read noise, detector cooling to below -90°C, an all-metal sealed design, and a Gigabit Ethernet interface that ensures fast data throughput. Furthermore, the availability of 100kHz non-EM mode operation means the cameras can also be used for steady-state applications with read noise as low as 2 e- rms. Princeton Instruments’ eXcelon3 sensor technology further extends the impressive utility of ProEM+ cameras for time-resolved, low-light applications.
