These sensors are mainly used for intern energy measurements in lasers with high repetition rates. They are characterized by a high sensitivity and they can be used in a wide wavelenght area. Sensor diameters between 4mm and 34 mm are available. The max. repetition rate depends on the diameter of the sensor and the used terminating resistor. Repetition rates of up to 3 kHz are possible.
