Fibre Optic Switch

The FOS Series fibre optic switch provides a convenient way to connect up to eight lasers to a single fibre-coupled instrument, such as the wavelength meters and spectrum analysers also provided by Bristol Instruments. It allows a single wavelength meter or spectrum analyser to characterise multiple lasers automatically. Complex experiments and multiple users can be easily accommodated.

The FOS is a self-contained microelectromechanical (MEMS) switch that operates from 400 to 1700 nm (VIS) or from 1000 to 2600 nm (NIR2). The switch is USB powered and controlled using a simple and intuitive PC application. Switching can be done manually, with the user selecting an appropriate channel,  or automatically by cycling through user specified channels.
