Fully automatic wavelength selector
FWS-Poly
The Flexible Wavelength Selector Poly (FWS-Poly) is a tunable filter that utilizes TwinFilm™ technology to provide simple software control (scan or set) of the center wavelength and bandwidth via USB communication. The bandwidth can be adjusted from 3 to 15 nm (nominal) depending on the specific model.
The FWS-Poly is compatible with any type of broadband lamp or ultra-continuous spectral source. Accessories are available here. For more information on compatibility, please contact us at info@hophotonix.com.
