Multi-Mode Fiber Coupler

   Aligning LASER light into the core of a multi-mode fiber requires submicron resolution and a high level of stability.  For this demanding task, most of today's fiber couplers are either flexure designs or motorized and automated alignment systems.  Both configurations are expensive.  The SM series of fiber couplers replaces these sometimes costly systems with a simple concept that creates a "light fulcrum" to increase the resolution of the system.  By using one of our standard fiber positioners, either the BFT-3 or CFT-3, and the OT.05-2 lens positioner, along with a stable connecting bracket, Siskiyou has created a robust and compact fiber alignment system.  The simplicity results in a less costly alignment solution. 

   The SM-BFC comes with a 20x objective and mounted focusing lens.  Holding a fiber requires one of our BFC series of bare fiber chucks, which are available in sizes to hold fibers from 80μm to 1mm.  A connectorized fiber version is available in the SM-CFT.  It comes with a 20x objective and mounted focusing lens, but requires our CFC connectorized fiber chucks, for fibers with SMA, NTT or ATT connectors.
