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 narrowband 

optical tunable filter that allows manual-tuning of 

center wavelength over X, O, S, C, & L bands. Its 

bandwidth ranges from 1.5nm to 0.1nm. The 

filter is built based on WL Photonics’ proprietary 

platform of “Crystal-Bench” with free-space 

diffraction grating. Manually wavelength tuning 

is done through a precise micrometer driver. Due 

to the optimized linear dispersion with the filter, 

the center wavelength of transmission band can 

be read easily from the micrometer. 

Unique optics design enables the filter to offer a 

great variation of bandwidth options, 

unprecedented & unsuppressed low insertion loss 

and polarization dependent loss (PDL) over main 

wavelength bands from 1000nm to 1700nm. 

Precise tuning mechanism enables filter to 

provide high wavelength resolution and excellent 

wavelength repeatability. Superior performance 

and compact footprint enable the filter to be a 

cost-effective wavelength-tuning solution for 

system integrations as well as laboratory 

purposes.
