WL PHOTONICS 波长可调窄线宽滤波器
WLTF-NM Manual Narrow bandwidth Tunable Filter 手动可调窄带滤波器The WLTF-NM is a Gaussian-shape narrowbandoptical tunable filter that allows manual-tuning ofcenter wavelength over X, O, S, C, & L bands. Itsbandwidth ranges from 1.5nm to 0.1nm. Thefilter is built based on WL Photonics’ proprietaryplatform of “Crystal-Bench” with free-spacediffraction grating. Manually wavelength tuningis done through a precise micrometer driver. Dueto the optimized linear dispersion with the filter,the center wavelength of transmission band canbe read easily from the micrometer.Unique optics design enables the filter to offer agreat variation of bandwidth options,unprecedented & unsuppressed low insertion lossand polarization dependent loss (PDL) over mainwavelength bands from 1000nm to 1700nm.Precise tuning mechanism enables filter toprovide high wavelength resolution and excellentwavelength repeatability. Superior performanceand compact footprint enable the filter to be acost-effective wavelength-tuning solution forsystem integrations as well as laboratorypurposes.Key Features?
