Flexible Wavelength Selector CenterLine

Flexible Wavelength Selector CenterLine

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 16 nm and one for compensating the beam direction offset.

Key product advantages:

  • Broad wavelength tuning
  • Fixed bandwidth (FWHM ~ 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.

Fixed Bandwidth Simplicity

Our simplest FWS provides manual adjustment of the center wavelength with a fixed transmission bandwidth, delivering economy and an ultra-compact format.

Simple Integration

Ultra-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.
