The main characteristic of this sensor is the very high sensitivity. With this it is possible to measure lowest laser powers with high precision. This sensor has a high linearity and in opposite to photo diodes no saturation effect at higher powers. The used black absorption coating allows the employment in a spectral range from 190nm up to 25µm. For stabilisation of the sensor we have used a thermal isolation of the sensor housing. Additionally the housing has a removable tube to protect the surface against strange light and air moving.
