Source: Fosco Connect Understanding Photoemissive Detectors Overview Photoemissive detectors, also known as photoelectric detectors, are devices that utilize the external photoelectric effect to detect light. They consist of a photocathode where incident light generates photoelectrons. These photoelectrons are then pulled away from the photocathode by an anode at a positive electric potential, resulting in a
