Tunable filter large spectral range, USB control, adjustable bandwidth 10 or 20 nm, center wavelength 255-1700 nm

The Flexible Wavelength Selector Poly-BLUE 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 is fixed at a nominal value of either 10 or 20 nm with high transmission capabilities.

LSL-FWS-A-Poly-BLUE is compatible with any type of broadband lamps or supercontinuum sources.
 

Key Advantages of the motorized automated tunable filter LSL-FWS-A-Poly-Red
- Fast software-controlled wavelength tuning
- Bandwidth fixed at 10 or 20 nm (nominal)
- Circular aperture: 5 mm or 10 mm
        - A5: 5 mm, suitable for lasers, supercontinuum lasers
        - A10: 10 mm, suitable for light sources with large beam size (tungsten-halogen, plasma, LED)
- High out of band blocking (OD 10) avoids unwanted spectral leakage and associated background noise typical of liquid crystal-based filtering systems

- Compact size

 

*For the optimal performance of the FWS, the incident light should be collimated.

*Poly-UV model can block up to 600 nm.
