It is an integrated module consisting of a MEMS chip, micro-optics and control electronics and interface. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tunable optical filter directs a selected channel to the. Thorlabs' optical filters include an extensive collection of dielectric-coated filters, colored glass filters, neutral density filters, spatial filters, tunable narrow bandpass Fabry-Perot filters, and tunable optical filters based on liquid crystal technology. For convenience, many of our optical. Everything you need to build an optical network from end-to-end. Thin-film filter and PLC based AWG for multiplexing, a full suite of components for optical amplification use, optomechanical or MEMS-based switches for protection or surveillance application, Tap PD for power monitoring and VOA for. POLATIS optical switch modules by HUBER+SUHNER, feature a non-blocking all-optical matrix, port counts from 16-48xCC, and "any-to-any" port connectivity. An optical filter selectively transmits one portion of the optical spectrum, while rejecting other portions. Commonly used in microscopy, spectroscopy, chemical analysis, and machine vision, Edmund Optics' optical filters are available in a variety of filter types and precision levels.
