Tapered fibers for optogenetics

OptogeniX probes are based on tapered optical fibers, for a very low-damage insertion into the brain. Light delivery on wide volumes or multipoint sites is based on a unique and proprietary technology, exploited by the following products:

  • Lambda-B fibers are ideal for illuminating large brain areas with enhanced homogeneity in comparison with standard flat-cleaved fibers. Provided as implantable fiber stubs, Lambda-B fibers can just replace standard implants with immediate gain in terms of stimulation efficiency, without any changes in your Optogenetics setup. Additionally, by inserting into the optical path one of the OptogeniX Launching Systems, it is also possible to sub-sample the target region and/or deliver different wavelength radiations at different locations without probe movements.
  • Side emitting fibers, or Sigma fibers, allow the illumination of small areas precisely localized along the taper edge. An OptogeniX Launching System must be employed to operate the selection of the emitting site. Shape, size and position of the windows can be customized to match experimental needs.
