New Compact High-Precision Single Mode Fiber Coupler

A new opto-mechanical tool for coupling light into single-mode fiber optics from Siskiyou Corporation offers a unique combination of high precision adjustment in a very compact package.  Specifically, Siskiyou single-mode fiber couplers incorporate optics for focusing laser light into a FC connectorized single-mode fiber optic, together with tip/tilt mechanical adjustment to permit accurate positioning of the focused beam with respect to the fiber end.  The use of ultra-high resolution, differential adjusters (2.75 arc-second movement per 5° adjuster rotation), together with a mechanical design that decouples tip/tilt adjustment from focus, delivers the precision necessary to achieve optimum coupling efficiency into single-mode fibers in a very small volume.  Alternately, the system can be used in reverse for high precision collimation of single-mode fiber output. 

Siskiyou single-mode fiber optic couplers will be useful for researchers and instrument builders who wish to couple laser output into single-mode fibers, or to produce small focused spots and collimated beams in a minimum of space.  The fiber optic coupler can also be easily integrated with Siskiyou beamsplitter modules, enabling entire multi-beam optical assemblies to be built in completely sealed configurations. 

Siskiyou Corporation (Grants Pass, OR) provides a diverse range of micromanipulators, microscope sample positioners, motion control systems and modular opto-mechanical mounts and positioners to life science and photonics researchers and OEMs.  The goal of the company is simple – to offer the highest quality product at an economical price, and to support customers with superior service.  Founded in 1972, Siskiyou is a vertically integrated company, performing all design, manufacturing, anodizing, and assembly in-house.
