Bandwidth-Adjustable Filters of WLTF-BAseries are built based on free-space optical Fourier transformation combing with diffraction grating. Unique optics design provides an access of selecting spatially desired spectral ingredients of input light and offers flat- top transmission spectral shape with flexible bandwidth and unprecedented low insertion loss and polarization dependent loss (PDL). Both center wavelength and bandwidth of transmission band can be tuned independently. Precise tuning mechanism enables filters to provide high wavelength resolution and excellent wavelength repeatability.

Manual version filter is available over X-, O-, S, C-, & L-bands. Center wavelength-tuning and bandwidth-adjusting of a transmission band are actuated by individual precise micrometer drivers separately. Due to the optimized linear dispersion with the filter, the center wavelength and bandwidth can be read easily from the micrometers. Electric version of such the filter is available only for OEM applications on request.
