FWS-High Resolution [Original Ver.]

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 (FWS) High Resolution is a manually tunable filter that provides smooth and precise manual adjustment; both the center wavelength and bandwidth are independently set with two multi-rotation manual dials for maximum resolution. An internal compensator maintains output alignment.

 

 

*Note : For the optimal performance of Wavelength Selectors, the incident light should be collimated.

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.
