We serve in Tuneable Filter Modules, Filter Cassettes and several other Filter

TFM/FC Wavelength Tunable Filter with Exchangeable Filter (Cassette Type)

TFM/FC contains an optical filter mounted on a cassette. By exchanging the cassette, TFM can change its spectral characteristics including the tunable wavelenth range. The center wavelength can be tuned until 20nm as the optical filter inside is turned by rotation of the equiped micrometer. The micrometer enable the fine wavelength tuning.
