First Sensor AG

High Precision Optical Sensors

First Sensor develops and manufactures a large selection of photodetectors with high-sensitivity, high-speed, and low-dark-current which can be adapted to your specific requirements. Our sensors are optimized for ultraviolet, visible, and infrared light as well as ionizing radiation. Package solutions include surface mount (SMD) and through-hole (THD) devices. Further, we provide silicon photomultipliers for the detection of lowest light levels.
