T (dB)

The LLTF is a non-dispersive, sub-nm
tunable bandpass filter that transmits a
single laser line while blocking unwanted
lines. It delivers the highest signal throughput in the industry. Output pointing is very
stable, removing the need to realign optical
setup. This filter is perfectly matched to our
TTNF for Raman applications. It is also
ideal as a pre-monochromator for triple
spectrograph. The LLTF is compatible with
any VIS-NIR broadband source. Free space
of fibered, the LLTF is the only tunable filter
with an isolation higher than OD4.
