From the input coupling of light using adjustable couplers to transmission via optical fibre assemblies to output coupling using focusable collimators - we can provide all of these capabilities.
Input couplers are used to couple collimated light into an optical fibre. The inner optic can be adjusted along three axes to allow laser beams with <nobr>Ø ≤10 mm</nobr> to be focused on optical fibres with a core diameter between <nobr>100 µm</nobr> and <nobr>2000 µm</nobr>.
The maximum power of the laser beam to be coupled is up to 150 W. The optics are also coated for the best power transmission; in fact, three wavelength ranges between 400 nm and 1300 nm are available. The optical connection of the fibre is carried out using an SMA connector.
Laser fibres: optical fibres are used in the transmission of optical power. We can assemble optical fibres to your specification.
Our product range comprises dual-clad fibres (quartz core/quartz cladding/hard clad/buffer) with fibre core diameters from 400 µm to 1000 µm. Different protective tubes are available, including flexible metal jackets or PVC and PTFE tubes. The fibre lengths vary according to customer specifications.
An optical connection is also available: for example, SMA connectors with free-standing fibres are available, either with ARCAP or copper ferrules. At <10 µm, the eccentricity of the fibre core to the ferrule’s outer diameter is very low. We are also able to provide the fibre end faces with an AR coating.
Output coupling collimators: in output coupling, the collimation of divergent light out of the connected fibre is important. The output coupling collimator, which is connected via an SMA connector, is used for this purpose. The optics used are adjustable along the z-axis and are available in three types of coatings from 350 nm to 1600 nm. To achieve different beam diameters, the output coupling collimators are available in various focal lengths.
When multimode fibres are used, the efficiency of the collimator is more than 85%.
