Flexible Wavelength Selector High Resolution

Flexible Wavelength Selector High Resolution

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.

Key product advantages:

  • Broad wavelength tuning
  • Precise bandwidth adjustment (FWHM 2 – 16 nm)
  • Circular uniform aperture
  • High (106) out of band extinction
  • Compact (40 x 76 x 50 mm)

Features

Uniform Circular Aperture

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

Precise Manual Adjustment

Separate multi-rotation dials enable precise manual adjustment 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.
