Tunable FBG Optical Filter (WTF-200)

The WTF-200 series wavelength tunable optical filter is based on a prioprietary compressivley-tuned fiber Bragg grating technology which follows a wideband tuning. The center wavelength is selectable, whilst the maxumum tuning range of the filter is typically 20nm. Custom filter with different shape, bandwidth and center wavelength is also available upon request, and customer supplied FBG can also be mounted into the WTF-200.
