Flexible Wavelength Selector Basic

Flexible Wavelength Selector Basic

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) 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.

Key product advantages:

  • Broad wavelength tuning
  • Smoothly adjustable bandwidth (FWHM 2 – 16 nm)
  • Circular uniform aperture
  • Compact rugged optomechanical package
  • High (106) out of band extinction

Features

Uniform Circular Aperture

Uniform circular aperture simplifies spectral filtering of images and illumination sources, avoiding the limitations of a typical monochromator slit geometry.

Simple Manual Adjustment

Separate knobs enable independent manual setting of both the center wavelength and the transmission bandwidth.

Simple Integration

Compact collinear geometry simplifies integration into microscopes, telescopes and cameras and other common photonic instruments.

High Extinction

High (106) out of band extinction avoids unwanted spectral leakage and associated background noise typical of liquid crystal based filtering systems.
