The Flexible Wavelength Selector Poly (FWS-Poly) is a tunable filter which utilizes TwinFilm™ technology to provide a simple software control (scanning or setting) of the center wavelength and the bandwidth via a USB communication. The bandwidth can be adjusted from around 3 to 15 nm (nominal) depending on the specific model.
FWS-Poly is compatible with any type of broadband lamps or supercontinuum sources. Accessories are available here. For more information about compatibility please contact us at firstname.lastname@example.org.
*Note : For the optimal performance of Wavelength Selectors, the incident light should be collimated.
*Note : FWS-Poly-UV model can block up to 600 nm.
