Overview
Narrowband Tuneable Filters of WLTF-NM- & WLTF-NE- series are built based on free-space optical Fourier transformation combing with diffraction grating. Patent-pending optics design offers great options of bandwidth with unprecedented low insertion loss and polarisation dependent loss (PDL). Precise tuning mechanism enables filters to provide high wavelength resolution and 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.
