PDF Introduction to Image Intensifier Tubes The terminology "image intensifier" and "image converter" are frequently confused. In par-ticular, image conversion refers to the transfer from an invisible to a visible spectral range, such as image converters used in night vision. On the other hand, image intensifiers which perform as the name suggests often also function as image converters.
