FWS-CenterLine 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 (FWS) CenterLine is a manually tunable filter that features two knurled knob – one for adjusting the center wavelength with a fixed bandwidth of around 15 nm 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.

Center Wavelength Adjustable

The center wavelength is adjustable to any value ranging between 255 nm ~ 1650 nm. (FWHM : 15 nm (nominal)) 

 

 

Simple Manual Adjustment

Separate knobs enable independent manual setting 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 extinction avoids unwanted spectral leakage

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