The filter characteristics of this module can be changed by exchanging the filter cassette. A fine tuning of wavelength ― within the range of 20nm ― is achieved by rotating the filter. The tuning mechanism employs a micrometer for an accurate wavelength adjustment.

Features
・The filter characteristics of the module can be changed by exchangeing the filter cassette.
・The TFM provides users a convenience in applications which require a variety of wavelength or FWHM.
Applications
■Wavelength selection in WDM system
This module can sharply select the demanded wavelength from a LED/ASE light source. The customers do not need to by the plural optical filters for the selection of the wavelength in the experiment by using this module.
■Simple narrow-band tunable light source
This product can be used as the narrow-band light source by combining with the LED light source or the ASE light source. By rotating the filter-cassette, this module works as a simple tunable wavelength light source.
Special Order Products
■Customized optical modules for R&D in the various wavelength areas.
Many customized modules have been realized in 360nm band, 500nm band, 850nm band, 980nm band,1064nm band.
