The Flexible Wavelength Selector (FWS) Poly-LV 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 connector. The center wavelength tuning range can be as wide as around ~500 nm or as narrow as ~50 nm depending on the specific model. The bandwidth can be adjusted from around 3 to 15 nm also depending on the specific model. FWS Poly LV is compatible with supercontinuum lasers from NKT Photonics, YSL Photonics, and Leukos. Accessories are available here.
This model is only compatible with lasers (depending on specifications).
Uniform circular aperture simplifies spectral filtering of images and illumination sources, avoiding the limitations of a typical monochromator slit geometry.
Automated and simple software control of the center wavelength and the transmission bandwidth. Supports custom wavelength scanning, setting and stepping.
Compact collinear geometry simplifies integration into microscopes, telescopes and cameras and other common photonic instruments.
High (106) out of band extinction avoids unwanted spectral leakage and associated background noise typical of liquid crystal based filtering systems.
