The Smallest Possible Spectrometer

The optical spectrometers and FBG interrogators of our FiSpec^® family are set apart by the fact that they combine a compact size with a high spectral resolution. The core of these systems is our unique FiSpec^® diffraction grating combining all components for optical imaging usually needed for a common spectrometer within a single fiber-integrated nanoscopic structure. Instead of a cumbersome and expensive macroscopic alignment of various optical components like slits, lenses, mirrors and optical gratings, we directly inscribe the functional spectrometer with our femtosecond laser process into the core of a standard telecom fiber. Enabled by this fully-automated, nanometer-precise and highly reproducible production approach we offer our customers an entry point into the space of spectrometery and fiberoptic sensing with an unprecedented quality and economic efficiency.
