WLTF-NM Manual Narrow bandwidth Tunable Filter
手动可调窄带滤波器
The WLTF-NM is a Gaussian-shape narrowband
optical tunable filter that allows manual-tuning of
center wavelength over X, O, S, C, & L bands. Its
bandwidth ranges from 1.5nm to 0.1nm. The
filter is built based on WL Photonics’ proprietary
platform of “Crystal-Bench” with free-space
diffraction grating. Manually wavelength tuning
is done through a precise micrometer driver. Due
to the optimized linear dispersion with the filter,
the center wavelength of transmission band can
be read easily from the micrometer.
Unique optics design enables the filter to offer a
great variation of bandwidth options,
unprecedented & unsuppressed low insertion loss
and polarization dependent loss (PDL) over main
wavelength bands from 1000nm to 1700nm.
Precise tuning mechanism enables filter to
provide high wavelength resolution and excellent
wavelength repeatability. Superior performance
and compact footprint enable the filter to be a
cost-effective wavelength-tuning solution for
system integrations as well as laboratory
purposes.
