Revolutionary Spectrometer & Fiberoptic Sensor Systems
Precise, miniature and cost-effective: FiSens debuts a new class of outstanding spectrometers and fully-integrated fiberoptic sensor systems.
Discover the Cutting-Edge of Fiber Optic Sensing
Micro-Spectrometer
We present the worldwide smallest high-resolution spectrometer. Built upon our proprietary fiber diffraction grating we offer powerful and compact fiberoptic interrogation systems at unprecedented price points. Unlock spectrometry at your fiber tip.
Fiberoptic Sensors
Measure multiple physical parameters along flexible and tiny optical fibers. Based on so called fiber Bragg gratings (FBG) you can customize up to 24 sensors at arbitrary fiber positions. Take advantage of fiberoptics virtues.
Multifunctional Sensing with a Single Optical Fiber
Strain
Our fiberoptic sensors measure strains as precise as 1 micrometer per meter and up to a maximum strain of 20.000 µm/m. By easily gluing the fiber onto a surface you can measure deformations along an object.
Pressure
Due to the Poisson effect our sensors also measure applied pressures or forces with high resolution. If pressed onto your wrist the fiberoptic sensor even measures as little pressures as the pulse of your heart beat.
Temperature
Sensing spatially distributed temperatures with only one fiber with high resolution of only 0,1K. Our pure silica optical fibers and fs-Laser written FBG sensors withstand even temperatures down to -180°C and up to 900°C.
Femtosecond Laser Processing
With ultrashort laser pulses we create precise microscopic structures within standard telecom optical fibers. By this we transform a simple waveguide into multifunctional sensors and spectrometers.
Fiber Optics Simplified
FiSens GmbH developes, manufactures and markets fully-integrated sensor systems based on fiberoptical spectrometers and fiber Bragg grating (FBG) sensor chains. We are a serial innovator of groundbreaking fiberoptic products enabling new kinds of applications in various industries. With our proprietary fully-automated femtosecond laser process we produce standardized as well as customized FBG sensors and spectrometers. Next to our off-the-shelf products available via online-shop we are used to work with OEMs to optimize our systems to their specific requirements.
FiSens GmbH was founded in 2017 as a spin-off from the Fraunhofer Heinrich-Hertz-Institute and formerly funded by the Photonics Incubator. Our founder team combines more than 30 years of technological experience in fiberoptic sensing and femtosecond laser physics. FiSens core technology has been patented and awarded.
