Laser beams can be flexibly transported to any point via optical fibers. Efficient coupling and decoupling of light into the fiber is an elementary task. Correct collimation of the laser beam is necessary when decoupling.

To simplify the work as much as possible, Futonics offers various developed fiber collimators. By using infrared optical materials, we maximize beam quality and efficiency. The product design is compact, adjustable and easy to use and is suitable for various optical applications.
Futonics Connector is our self-made product. It has a special anti-reflective coating required for the 200 W laser to ensure high output power and reduce losses.
