The Flexible Wavelength Selector utilizes TwinFilm™ technology to deliver the tunable wavelength filtering characteristics of a grating monochromator together with the circular aperture imaging capabilities of a bandpass filter.
The Flexible Wavelength Selector (FWS) High Resolution is a manually tunable filter that provides smooth and precise manual adjustment; both the center wavelength and bandwidth are independently set with two multi-rotation manual dials for maximum resolution. An internal compensator maintains output alignment.
