20 Nov 2009 The FISBA Beam Twister™ (FBT) is based on a patented technology by FISBA. This unique beam symmetrization unit is typically used in the fiber coupling of a diode laser bar for example. The FBT combines an FAC lens with a beam rotating lens array to provide you with nearly diffraction limited collimation and highest efficiency. Depending on your requirements, FISBA offers you all optical components or complete optical systems such as focussing optics for fiber-coupling as Facet-to-Focus (F2F) solutions. |
