    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
