Acousto-optic tunable filter for fiber optics
Fianium

The AOTF system is a removable module that enables up to 8
simultaneous tunable wavelength channels to be selected from
the SC400 or SC450 broadband output. There is a choice of three
AOTF crystals that cover the entire supercontinuum spectrum
from 400nm to beyond 2μm.
Output is a free-space, collimated beam or, optionally, coupled to
single-mode polarisation maintaining fiber.

The AOTF Dual system houses two AOTF crystals to provide an
even wider tuning range from a single supercontinuum input. The
system can be configured with any two of the AOTF crystals; VIS,
NIR1 or NIR2.
With the addition of a second AOTF controller, both outputs can
also be controlled independently and simultaneously using the
supplied software.

The new High Power version uses a unique design to avoid
the traditional polarisation loss associated with AOTF systems
used with supercontinuum lasers. Ideally suited to applications
demanding the highest power throughput the AOTF-HP provides
over 70% of the full supercontinuum spectral density.
