iXon^EM+ 885 EMCCD Camera

885

A proud member of Andor’s iXonEM+ EMCCD range, the 885 benefits from the unique innovations and high-end performance specifications that have characterized this camera family as the industry’s leading high-performance EMCCD.

The megapixel sensor format and 8 x 8μm pixel size of the 885 presents an attractive combination of field of view and resolution, offering excellent Nyquist over-sampling for cell microscopy.

When more light is available from the sample, the EMCCD gain can be completely switched off and the camera operated as a 'traditional' CCD camera. However if the camera is used in low-light conditions, the EMCCD gain can be applied to render it single photon sensitive, while maintaining a full resolution frame rate of 31 frames/sec. The absolute EM gain multiplication can be varied linearly from unity up to a thousand times directly via RealGain^TM, a true quantitative EM gain scale.

  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 -95°C

  Critical for elimination of darkcurrent detection limit.

• > 65% QE from Virtual Phase Sensor

  Highly efficient photon collection. One window design.

• Variable Readout Rates Up To 35 MHz

  Quantitative accuracy at all speeds.

• 8 x 8μm Pixel Size (Fully Binnable)

  Excellent balance of NyQuist resolution and photon collection.

• UltraVac™

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

• Minimal Clock-Induced Charge

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

• Enhanced Baseline Clamp

  Essential for quantitative accuracy of dynamic measurements.

• Negligible EM Gain Ageing

  No requirement for gain recalibration.

• Built-in C-mount Compatible Shutter (Optional)

  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.
