Inper offers a lightweight optogenetic fiber with a standard FC/PC or SMA connector on one end for connecting fiber photometry system, and Ø1.25 mm or Ø2.5 mm ferrule on the other end for connecting Fiber Optic Cannula via a mating sleeve.
Conventional fiber cables have strong autofluorescence due to the production process. In fiber photometry experiment, excessive background fluorescence will interfere with the acquisition of the target fluorescence signal. For the unique requirements of fiber photometry experiments, inper improves production technology, which greatly reduces the autofluorescence intensity of the fiber end face.
Super miniaturized ferrule tailstock
Inper have optimized the ferrule tailstock to make it smaller. The out diameter of 1.25 mm ferrule tailstock is only 1.9 mm, and the out diameter of 2.5 mm ferrule tailstock only 2.9 mm, which is more suitable for close-range multi-site recording and stimulation during experiment. The tailstock is not-magnetic, compatible with fMRI experiments.
Choice of NA
The numerical aperture (NA) is the ability of the end face of the fiber to accept light and also determines the angle at which the light is emitted from the fiber.
In optical fiber recording experiments, large numerical apertures can acquire more fluorescence signals.
Inper offers a variety of fiber options with different numerical apertures. The incident and emission angles for different NA are shown in the figure (Fiber-Air Interface).
Compatibility of Optogenetic Fiber, Fiber Optic Cannula and Mating Sleeve
The matched mating sleeve should be employed to connect fiber optic cannula and optogenetic fiber. The Ø1.25mm fiber optic cannula should be connected to optogenetic fiber using an inside diameter of 1.25mm mating sleeve, while the Ø2.5mm fiber optic cannula should be connected to optogenetic fiber with a an inside diameter of 2.5mm mating sleeve.
Inper provides optogenetic fiber of various standard lengths including 0.5m, 1m, 1.5m, 2.0m, 2.5m, 3.0m, 3.5m 4.0m, 5m. For other custom requirements, please contact support@Inper.com
Inper also offers mono and branching optogenetic fibers for single site or bilateral sites recording.
