iXon^EM+ EMCCD Camera

860

The iXon^EM+ DU-860 back-illuminated EMCCD has single photon detection capability without an image intensifier, combined with greater than 90% QE of a back-illuminated sensor. Containing a 128 x 128 Frame Transfer CCD sensor from E2V Technologies, it enables charge to be multiplied on the sensor before it is read out, while utilizing the full QE performance of the CCD sensor. The absolute EMCCD gain of the camera can be varied linearly from unity up to a thousand times directly through the software, via a true quantitative EM gain scale. Andor are the first to offer this technology as a complete, software controlled system for scientific digital imaging applications. The system offers up to 10 MHz pixel readout rate, both EMCCD and conventional amplifier outputs and benefits from minimized dark current with unequalled thermoelectric cooling down to -100°C.

  Absolute EMCCD gain selectable directly from a linear and quantitative scale.

• iCam

  Unique innovation that empowers the EMCCD to operate with market-leading acquisition efficiency through live cell microscopy software.

• TE Cooling to -100°C

  Critical for elimination of darkcurrent detection limit.

• > 90% QE Back-Illuminated Sensor

  High detector sensitivity.

• Variable Readout Rates Up To 10 MHz

  Quantitative accuracy at all speeds. Slower readout rate for enhanced 16-bit dynamic range.

• 515 Full Frames per Second

  Ideal for highly dynamic, low light experiments.

• UltraVac™

  Critical for sustained vacuum integrity and to maintain unequalled cooling and QE performance, year after year.

• High Dynamic Range & Amplification

  Extended sensor dynamic range (readout speed dependent) and matched digitization (16-bit available) for quantization of dim and bright signals.

• Minimal Clock-Induced Charge

  Giving lowest “spurious noise” specification; essential for single photon counting.

• Enhanced Baseline Clamp

  Essential for quantitative accuracy of dynamic measurements.

• Built-in C-mount Compatible Shutter

  Easy means to record control dark images - excellent for optimization of experimental set-up.

• Cropped Sensor Mode

  Specialized readout mode for achieving sub-millisecond temporal resolution from EMCCD and CCD cameras. Intuitive Cropped Sensor definition for continuous rapid image or spectral acquisition.
