Wideband Tunable Filters of WLTF-WM- & WLTF-WE- series are built based on free-space optical Fourier transformation combing with diffraction grating. Unique optics design produces an access of selecting spatially desired spectral ingredients of input light and offers flattop transmission spectral shape with flexible bandwidth and unprecedented low insertion loss and polarization dependent loss (PDL).

Precise tuning mechanism enables filters to provide high wavelength resolution and excellent wavelength repeatability. Both of manual and electric version filters are available over X-, O-, S-, C-, & L-bands. Wavelength-tuning is actuated by either a precise micrometer driver or a built-in micro motor connected to a PC through a USB (I²C or SPI) interface in which actuation is monitored by a built-in encoder and controlled dynamically in a closed-loop. Motor control software is provided.
