A phototube or photoelectric cell is a type of gas-filled or vacuum tube that is sensitive to light. Such a tube is more correctly called a 'photoemissive cell' to distinguish it from photovoltaic or photoconductive cells. Phototubes were previously more widely used but are now replaced in many applications by … See more Phototubes operate according to the photoelectric effect: Incoming photons strike a photocathode, knocking electrons out of its surface, which are attracted to an anode. Thus current is dependent on the frequency and … See more One major application of the phototube was the reading of optical sound tracks for projected films. Phototubes were used in a variety of light … See more WebThe most common types of UV Sensors include: UV Phototubes People use them to detect UV levels in water and air treatment facilities. They use a phototube (photoelectric/photo-emissive cell) to detect ambient UV radiation. The phototube is often a vacuous cylindrical bulb. However, it can also be gas-filled . hinduism compared to buddhism
