FWS-High Resolution [Old 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.

Bandwidth and Wavelength

You can choose the transmission bandwidth and wavelength anywhere in the informed range.

 

 

Precise Manual Adjustment

Separate multi-rotation dials enable precise manual adjustment of both the center wavelength and the transmission bandwidth.

Imaging Detection

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

 

 

   

 

 

High Out-of-band Rejection

High (10-6) out of band rejection avoids unwanted spectral leakage

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