Flexible Wavelength Selector Poly

Flexible Wavelength Selector Poly

The Flexible Wavelength Selector (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 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 is compatible with any type of broadband lamps or supercontinuum sources. Accessories are available here. For more information about compatibility please contact us at support@spectrolightinc.com.

For all the models of FWS Poly, we provide Laser Version which gives the same performance at a lower cost.

Key product advantages:

  • Fast software controlled wavelength tuning
  • Software bandwidth adjustment (FWHM 3 – 15 nm)
  • Circular aperture
  • High (106) out of band extinction
  • Compact (170x129x200 mm)

Features

Uniform Circular Aperture

Uniform circular aperture simplifies spectral filtering of images and illumination sources, avoiding the limitations of a typical monochromator slit geometry.

Simple Software Control

Automated and simple software control of the center wavelength and the transmission bandwidth. Supports custom wavelength scanning, setting and stepping.

Simple Integration

Compact collinear geometry simplifies integration into microscopes, telescopes and cameras and other common photonic instruments.

High Extinction

High (106) out of band extinction avoids unwanted spectral leakage and associated background noise typical of liquid crystal based filtering systems.
