The FISBA Beam Twister™ (FBT) is the perfect solution for beam symmetrization when efficient fiber coupling of diode laser bars is needed. FISBA, a Nalux alliance partner, offers pre-assembled Twister Array and FAC products, as well as the manufacturing of Twister Array components for your own assembly process. Thanks to a high refractive index, we are able to achieve improved coupling efficiency.
Pitch distances: 400 µm and 500 µm
Wavelength: 790 – 990 nm (customer-specific wavelength available on request)
Lengths for standard bars: 12 mm
Customized tab designs upon your request
Nalux stocks standard optical elements for the BTU for a pitch of either 400μm or 500μm and can design and manufacture the optics needed for a customized pitch
