Electron Detector

The Electron Detector was designed for direct digital recording of data from biological electron microscopy. The sensor, based on active pixel technology, is a substitute for conventional wet-film recording methods featured in electron microscopy and is readily incorporated into a camera system. 






The electron came from a project aiming to design and build a new camera system for electron microscopy. The project provided a vastly improved substitute for conventional wet film. The electron detector, with integrated readout and control circuitry, provides fast, high resolution digital imaging and storage.



  • The monolithic active pixel sensor is manufactured using conventional CMOS technology, meaning mass production is easily achieved

  • High resolution imaging: 1-5 microns

  • Capable of withstanding radiation doses exceeding 15kRads

  • Sensor detects a wide range of ionising radiation without the need for intermediate elements, or a resolution-limiting phosphorescent scintillation screen

  • Offers greatly improved pixel fill factor and resolution of the three dimensional structure of macromolecules



  • The detector was designed primarily for use as digital imaging and data storage for electron microscopy, particularly transmission and cryo-electron microscopy.

  • High radiation resistance makes the detector suitable for use in radiation harsh environments such as decommissioned nuclear facilities and satellites
