Si PIN photodiodes feature low capacitance, which enables them to deliver a wide bandwidth with only a low bias voltage, making them ideal for high-speed photometry as well as optical communications. When connected to a high-speed preamplifier, their low terminal capacitance ensures a wide response speed and lower noise. Various types of PIN diodes are available, including those with a mini lens. which increases fiber coupling efficiency and enhanced violet sensitivity for violet laser detection.
