Flexible band width and wavelength
Flexible Wavelength Selector

Direction

Based on SLI patented TwinFilm™ technology, the Flexible Wavelength Selector is a uniquely compact opto-mechanical device that combines the wavelength tuning and bandwidth adjustment of a grating monochromator with the imaging advantages of a large aperture filter. With both high (10⁶) out of band extinction and excellent (> 75 %) transmission, the Flexible Wavelength Selector is a simple, turnkey solution for any imaging applications that require wavelength control, with products covering the extended visible spectrum. Plus the in-line configuration, together with internal correction of alignment (deflection/walk-off), means the FWS is simple to integrate with cameras, microscopes and other instruments.

• FWS-Auto models
  feature complete software control of wavelength and bandwidth via a USB link and simple software interface.
• FWS-Basic models
  provide manual control of wavelength and bandwidth via knurled knobs.
• FWS-CenterLine models
  provide manual control of wavelength with a factory pre-set bandwidth (~17 nm FWHM).
• FWS-High Resolution models
  provide manual control of wavelength and bandwidth using multi-rotation precision dials.
