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.

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

 

*Note : F00 - F02 models can block up to 600 nm.

Broadband Tunable Spectral Wavelength and Adjustable Bandwidth

The broadband range of the wavelength and the transmission bandwidth can be adjusted by 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 Rejection

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

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