QuantEM™ 512SC Datasheet HIGH PERFORMANCE EMCCD & CCD CAMERAS FOR LIFE SCIENCES 512 x 512 imaging array 16 x 16-μm pixels The Photometrics® QuantEM™ 512SC is the world’s first and only electron-multiplying CCD (EMCCD) camera to offer on-chip signal amplification with true quantitative stability across 16 bits at readout rates of 10, 5, and 1.25 MHz. The high-speed, highperformance QuantEM lets you conduct precision ratiometric analysis in time-course experiments, acquire reproducible data during long-term studies, and capture streaming data for multidimensional time-lapse investigations — all with single-molecule sensitivity. A patent-pending PAR™ feedback system provides exceptional stabilization of EM gain, while an intelligent FPGA design facilitates self-calibrating linearization of EM gain and prevents bias drift over time. Furthermore, patentpending ACE™ technology enables superior timing resolution of the device’s pixel clocks, allowing optimal signal-to-noise sampling and minimizing spurious charge.
