FISBA B e am Tw ister™ (FBT)
The FISBA Beam Twister ™
Scope
(FBT) is an innovative beam
· · Laser diode pitch: 100–1000 µm
twisting element meant to
· · Emitter width: up to 50% fill factor
generate an almost symmetri-
· · Numerical aperture: 0,7 in the fast axis, 0,1 in the slow axis
cal beam profile. The flexible
design of the FBT module
Applications
makes it possible to use the
· · Fiber coupling of high brightness laser diodes
FBT with a variety of different
· · Pumping units for fiber-laser
laser diodes in regard to
· · Beam shaping systems
emitter width and pitch,
· · Micro illumination
tailored specifically to your
· · Light focussing systems
application.
