It is a wavelength selector that allows control of the center wavelength and bandwidth using the proprietary TwinFilm technology. It is an electrically operated model that can be easily controlled via software.
The FWS-Mono series is an electrically adjustable filter controlled by software, utilizing the unique TwinFilm technology. It allows for easy control of the center wavelength and bandwidth via USB, and scanning is also possible. While the wavelength selection range is relatively narrow, it offers a rich variety of wavelength models. It is compatible with various broadband light sources and supercontinuum light sources, making it usable as a wavelength-variable light source. 【Features】 - Electric model - Extensive wavelength lineup - Quick wavelength tuning - Wavelength scanning capability - Excellent transmittance > 75% - High out-of-band extinction ratio (10^6) - Adjustable bandwidth from 3 to 15 nm - Uniformity over 95% of a large aperture (up to Φ10 mm) - No walk-off even when the wavelength changes, thanks to the offset correction optical system - Easy installation
