【Overview】
Series LP low power thermopile detectors, manufactured by SLT Sensor- und Lasertechnik GmbH (Germany). The outstanding feature of this series is their very high sensitivity: high precision measurement over a dynamic range of more than 5 orders of magnitude, high linearity and no saturation effects at higher powers. The broadband absorption layer allows use between 190nm and 25µm without significant wavelength dependence.
【Key Features】
(1) Very high sensitivity, dynamic range >5 orders of magnitude;
(2) High linearity, no saturation effects;
(3) Broadband absorption layer 190nm-25µm;
(4) Detection threshold down to 10-50µW;
(5) Optional thermal isolation housing and removable lens tube (fibre adapters available);
(6) E-Connector with EEPROM.
【Typical Applications】
Low power cw laser measurement, precision detection of weak laser power, fibre laser power monitoring.
