Tunable Bandpass Filters
The Flexible Wavelength Selector (FWS) is the optical tunable bandpass filter that uses patented TwinFilm™ technology to control both center wavelength and bandwidth.
The FWS Manual and Auto type has a wide selection of wavelength ranges of UV, VIS, NIR, and SWIR and will work with any collimated light sources to produce a continuously tunable light source, and there’s no calibration or alignment is required. It has both high (OD 10) out-of-band blocking and excellent (>75%) transmission.
The FWS is a simple, turnkey solution for various applications that require specific wavelength excitation and detection throughout the extended wideband spectrum (255 – 1700 nm) and has the potential to integrate with broadband light sources, cameras, and other instruments, resulting in Tunable light sources, Hyperspectral imaging, and other applications.
The strengths of our FWS series can be confirmed by comparison with similar products. Please refer to the application note for more details. Click Here!
