Inexpensive fiber coupler available for quartz fibers

LASER COMPONENTS presents a new product made inhouse: Easy to mount fiber couplers for laser systems, facilitating the coupling of light from free-beam lasers easliy into a quartz fiber.

Using a mounting flange, the coupler is directly attached to the laser. It is possible to couple laser beams with a diameter of up to 10 mm into fibers with core diameters ranging from 100 μm to 2000 μm.

Only a fine adjustment is necessary to use the whole system: Using adjustment screws, it is possible to adjust the optics on the inside of the coupler along the x-axis and the y-axis or to tilt them. In addition, adjusting the optics along the z-axis is done via a knurled wheel.

The fiber coupler is suitable for the wavelength range from 400 nm to 1300 nm. The optics on the inside can be equipped with different AR coatings: 400 nm to 700 nm, 633 nm to 1064 nm, or 800 nm to 1300 nm.
