To explain the photoelectric effect, it is essential to mention the corpuscular model of light. This device, comprising a gas photocell, can address different concepts related to this model mainly the quantum efficiency, the sensitivity of the cathode and the influence of intensity on the maximum output current. Ready to use, adaptable on optical bench with its Ø = 10 mm diameter rod, this housing is ideal for showing that light is composed of photons.
