FWS-Basic new

The Flexible Wavelength Selector utilizes TwinFilm™ technology to deliver the tunable wavelength filtering characteristics of a grating monochromator together with the circular aperture imaging capabilities of a bandpass filter.

 

The Flexible Wavelength Selector Basic (FWS-Basic) is a manually tunable filter that features three knurled knobs – two for adjusting the center wavelength and the transmission bandwidth and one for compensating the beam direction offset.

Broadband Wavelength and Adjustable Bandwidth

The broadband range of the wavelength and the transmission bandwidth can be adjustable by a manual control.

 

 

Simple Manual Adjustment

Separate knobs enable independent manual settings of both the center wavelength and the transmission bandwidth. (Gear 1:1)

 

 

Imaging Detection

Simple integration into microscopes, telescopes, cameras, light sources and other common photonic instruments. 

 

 

   

 

 

High Out-of-band Extinction

High (106) out-of-band extinction avoids unwanted spectral leakage and

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