Probes for Spectrometers

Different measurement situations require different probes to suit the application at hand. This is precisely why Polytec offers a selection of scan heads that can be used in direct contact with and even at a greater working distance from the goods being measured. Probes that can be immersed in the product to be analyzed are also available. Some sensors have already been combined with an illumination module and have an internal reference. Using a multiplexer system with fiber-optic switches, a spectrometer can be equipped with several probes which are used at different measurement points.


The PAS-H-A03 distance scan head is a reflection scan head that allows the user to carry out sample measurements at distances of between 150 and 600 mm. This makes it ideal for analyzing goods being measured on conveyor belts, for strip products and for similar applications. The scan head has a combined illumination and sensor unit as well as an integrated reference.
