TRENTON, N.J., Jan. 28, 2011 — A professional-grade electron multiplying (EM) CCD camera for spectroscopy applications has been unveiled by Princeton Instruments. The ProEM:1600, the latest addition to the ProEM line, uses proprietary eXcelon technology that reduces the interference fringes (i.e., etaloning effect) that have made back-thinned EMCCDs unusable in the near-infrared, and increases the sensitivity of the detector in the UV, blue and NIR spectral regions.
The camera features 16-µm pixels in 1600 × 200 and 1600 × 400 formats. The high-speed, electron-multiplying mode captures fast dynamics, and the traditional CCD mode delivers ultralow read noise for high-precision photometry. The 6.67-MHz readout rate and 1.5-µs vertical shift time produce acquisition rates of >3000 spectra/s.
Applications include scanning confocal Raman spectroscopy, hyperspectral imaging and single-molecule spectroscopy. A new software feature virtually eliminates frame-to-frame instability, even at high spectral rates.
The camera includes a Bias Active Stability Engine, proprietary Noise Suppression technology and OptiCAL on-demand EM gain calibration via a built-in light source. A hardware-generated time stamp on each frame takes the guesswork out of time-resolved photometry.
The all-metal-seal vacuum design delivers deep thermoelectric cooling and low dark current, and vacuum performance is guaranteed for the lifetime of the camera. It is cooled with air, liquid or a combination of the two. For vibration-sensitive applications, maximum cooling can be achieved using liquid recirculation, eliminating fan vibration.
The latest Gigabit Ethernet interface enables remote operation via a single cable without the need for custom frame grabbers. The camera operates on 32- and 64-bit Microsoft Windows operating systems and is fully supported under LightField, Princeton Instruments’ 64-bit data acquisition software that features the patent-pending IntelliCal spectral calibration routine.
