Designed for the “Optics” section to study the photoelectric effect and calculate the Planck constant, this set features a 230 V / 50 Hz ultraviolet radiation source. It includes three plates—zinc, copper, and a metal mesh in a frame—each measuring at least 80 x 80 mm to effectively block radiation flux. Every plate is mounted on a dielectric stand equipped with power connection terminals. Additionally, the emitter is fitted with a specialized nozzle to precisely direct the UV flux onto the plates.
