An ultra compact supercontinuum white light source with broadband, diffraction-limited output from the UV to the IR (400 to beyond 2000 nm), the SuperK™ manufactured by KOHERAS A/S of Birkerød, Denmark, is based on a proprietary compact pump laser design and a patent-pending dual wavelength pumping scheme.
It also provides continuum radiation in the technologically important blue and near-UV spectral regions. Previous supercontinuum light sources that could provide this coverage were based on Ti:Sapphire-laser-pumped systems and were expensive, very large and complicated to operate. Available in a rugged turn-key system and OEM solution, the SuperK™ is the first and only source in the market, which is economically suitable for industrial volume application.
The turnkey light source integrates easily into instruments and systems for industrial measurement tasks and for general use as a research tool. It also is suitable for high-resolution optical coherence tomography, where it performs rapid scanning in the medical environment, and for white light interferometry, where it determines the displacement or the chromatic dispersion in fibre and planar waveguides with high accuracy.
Another application is to be found in a growing market for the High Resolution 3D non contact Surface Metrology segment, where a Xenon lamp has been used before. But due to a low intensity of the Xenon lamp these system can not deliver a High Resolution image. With the new light source KOHERAS SuperK™ the surface metrology system can deliver an image at a much higher resolution than it has ever been shown before.
