The Flexible Wavelength Selector (FWS) Mono is a tunable bandpass filter which utilizes TwinFilm™ technology to provide a simple software control (scanning or setting) of the center wavelength and the bandwidth via USB software. The bandwidth can be adjusted from 3 to 15 nm depending on the specific wavelength.

Key product advantages:
-Fast software controlled wavelength tuning
-Software bandwidth adjustment (FWHM 3 – 15 nm)
-Out-of-band Blocking OD 6 (0.00001 % transmission)
-Wide spectral range 255 - 1650 nm
