Energy sensors without housing0 pages
Energy sensors without housing The main application for this type of sensor is energy moni-toring of high repetition rate lasers. The co-axially built sensors have a high sensitivity and can be applied in a wide spectral range. Detector diameters between 4 mm and 34 mm are available. The maximum repetition rate depends on the sensor diameter and the load resistor; val-ues up to 3000 pps. are possible.
