    Ball lens Raman fiber-optic probe is a new addition to art photonics’ FlexiSpec® product line.
    The technology of direct deposition of the dielectric filters at the fiber end faces enables miniaturization of the fiber-optic probe head without compromising its performance.
    It makes possible to develop a cost-effective Raman probe for endoscopic and other applications.The fiber optic Raman probe is produced for multiwave excitation in the range 690-785 nm, e.g. @785nm – “Finger print” spectral range with fluorescence reduction, and @690nm – “High wavenumber” spectral range for conventional Raman spectrometers.
