These new focused beam sensing fibers detect minute targets. They allow users to "pipe" light into otherwise inaccessible locations.The fibers come in both fixed and adjustable sensing distance models.
The L4C6 and L4C20 convergent lens attachments allow sensing at fixed focal distances of 6 and 20 mm, respectively, when used with a bifurcated coaxial fiber. Spot diameters as small as 0.25 mm can be achieved with the L4C6 lens, allowing sensing of very tiny targets.
