Germany 4H JENA sensor 4H JENA model 4H JENA price

4H JENA sensor is a device that converts optical signals into electrical signals. Its working principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon where electrons in a material absorb the energy of photons when light shines on certain substances, resulting in corresponding electrical effects. Based on the different phenomena of the photoelectric effect, it is divided into three categories: external photoelectric effect, internal photoelectric effect, and photovoltaic effect. Photoelectric devices include phototubes, photomultiplier tubes, photoresistors, photodiodes, phototransistors, and photocells. The performance and characteristic curves of photoelectric devices are analyzed. 4H JEN
