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.
