    Image Intensifiers - (10 companies)
    Image intensifiers are devices used in low light cameras to enhance image capturing capabilities when only ambient light sources are available. This is done mainly by proportionately increasing the number of electrons during the photon to electron conversion. Image intensifiers are commonly used to assist in the visual imaging of X-rays, gamma rays and infrared light. Learn More

  • Radiation Detectors-Image
    Radiation Detectors - (205 companies) reflected through a lens and makes contact with a photocathode, a specialized device which produces electrons when contacted by light. The electrons are pulled through a photomultiplier and are collected by an anode to form an electromagnetic pulse... Search by Specification | Learn More
  • Low Light Cameras - (163 companies) a photocathode. The electron count is enlarged by the use of a microchannel plate, and the electrons are accelerated by a voltage in the microchannel plate. On average, one photon is recorded as 1,000 electrons after this process. ICCD cameras have... Search by Specification | Learn More
