Poly-RED-A5 new

The Flexible Wavelength Selector Poly-RED (Poly-RED) 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 2 to 15 nm (nominal) depending on the specific model.


Poly-RED is compatible with any type of broadband lamps or supercontinuum sources. Accessories are available here. For more information about compatibility please contact us at info@spectrolightinc.com.


A5 : Suitable for lasers, supercontinuum lasers

A10 : Suitable for light sources with large beam size (tungsten-halogen, plasma, LED)


/ Key Product Advantages

  • Fast software-controlled wavelength tuning
  • Software bandwidth adjustment (FWHM 2 - 15 nm, nominal)
  • Circular aperture (5 mm)
  • High out of band rejection (OD 10)


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


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

Broadband Tunable Spectral Wavelength and Adjustable Bandwidth

The broadband spectral range of the wavelength and the transmission bandwidth can be adjusted via quick and easy software control.



High Out-of-band Blocking

High out-of-band blocking (OD 10) avoids unwanted spectral leakage and

associated background noise typical of liquid crystal-based filtering systems.
