The blank optical fiber PICFIB2 is compatible to the PICO device series (PICO-connector). It can be utilized for the readout of contactless sensors such as sensor spots (e.g. OXSP5) or oxygen sensitive nanoparticles (OXNANO). The fiber length is 1m. With the outer protection rubber, the diameter is roughly 3mm. The large diameter of the fiber itself (2mm) enables measurements through 0-10mm thick transparent materials.
