Properties of the LOF fiber

1. Cladding protection through orifice effect of the prismatic element, resulting in a long service life even with laser variations (mode, power output, beam quality, thermal lens), excess core radiation input and heavy reflections on the work piece. This forms the basis for exactly holding the fiber input and output positions in directions x, y, z (plug & play).
2. Coupling-in of the laser radiation can be done at process power level, thus optimization and shortening of the coupling-in operation.
3. Dynamic length compensation between plastic materials and quartz glass in the presence of temperature changes. No microbending, operational as well as external temerature stresses have no negative influence. Minimized stresses in the region of the bared fiber and the prismatic element. An alteration of the homogenous irradiation characteristics due to any movements of the cable in the exit area is absolutely impossible.
4. The air-assisted cooling supports the optimum function of the prismatic element. Cooling and self-cleaning effects at the fiber input and output zones as well as at the inner face of the protective glass. All optical elements in the beam input and output zones are actively cooled. Owing to the air-assisted cooling, a significantly extended temperature range of the optical elements (for instance -20°C to +300°C) can be opened up. No stress cracking owing to the use of air as cooling medium. Evacuation of any ions or released particles through constant air regeneration.
