Ascent® ASP-A340 640 x 480 7.4u

This product is no longer available.

  • 1 to 16 MHz 16-Bit digitization
  • Binning up to 8 horizontal x 484 height
  • Field upgradeable firmware
  • Subarray readout and fast sequencing modes

The Ascent A340 has a 1/3" format interline transfer sensor with high quantum efficiency and twice the dynamic range of similar Sony sensors. The camera is available with a monochrome sensor (A340) or color sensor with a Bayer mosaic (A340C). Low noise and small pixels are ideal for OEM applications, biological and physical sciences, guiding/adaptive optics and other high frame rate applications.  


Additional Features:

  • 32/64 bit ActiveX drivers included with every system
  • Programmable cooling to 35°C below ambient
  • External triggering and strobe controls
  • Programmable offset and gain
  • Programmable status indicators
  • Dual channel CCD support
  • Moisture free chambers
  • Video focus mode
  • Precision locking filter wheels optional
