Patented technology by FISBA - FISBA BEAM TWISTER™ - Optical components - Products - FISBA OPTIK - St.Gallen - Switzerland
The FISBA Beam Twister™ (FBT) is an innovative beam shaping element for generating an almost symmetrical beam profile with a better performance than other comparable fiber coupling systems. The beam twisting concept developed and patented by FISBA consists of a FAC lens with a beam rotating lens array for nearly diffraction limited collimation and highest efficiency. For this purpose FISBA developed micro-optics for the individual beam twisting of each emitter of the diode laser bar to achieve an almost round beam profile.

The flexible design of the FBT unit offers the customer a multitude of executions for laser diodes in regard to pitch and emitter. FISBA offers its customers the complete optical solution from the simple component to the complex and customized optical system for Facet-to-Focus (F2F) solutions such as fiber coupling or beam collimation.

Laser diode pitch: 100 – 1000 µm
Emitter width: <50% fill factor
Numerical aperture: 0.7 in fast axis, 0.1 in slow axis
