Optoelectric Cannulas - single electrode
-
The most straightforward configuration comprises a single 200 µm core diameter optical fiber of 0.22 NA and a 75 µm diameter metallic wire of 3MΩ impedance as an electrode. A grooved 1.25 mm zirconia ferrule has optical fiber in its central hole and the electrode embedded in its groove. The contacts with corresponding optoelectric patchcord are maintained with a bronze sleeve.
Other optical fiber, electrode types and multiple electrodes or even multiple fiber configurations are available upon request.
Notes:- The electrode protrusion is the distance (mm) between the fiber tip and the electrode tip. Positive protrusion indicates the electrode is more prolonged than optical fiber.
- Stereotaxic Cannula Holders and Ferrule Receptacle adapters are available for implantation to secure the Mono Optoelectric Cannulas (SCH and FCA).
- More information on our electrodes can be found in this document (PDF).
