The key feature of these measuring head series is the high sensitivity. It allows you to make high precision measurement over a huge dynamic range (up to 5 dimensions) with high linearity and, in contrary to a Photodiode, without a saturation effect at high power levels. The broadband absorbing layer allows use between 190 nm and 25 µm without appreciable wavelength dependence.
