The wide spectral coverage of the SuperK sources lends the technology for many applications in test and measurement. Applications such as optical fiber characterisation, fiber-optic component testing and material analysis are just few of the fields SuperK technology has been employed. With the SuperK being ultra-broadband and the excellent single-mode, Gaussian beam characteristics, the light can be easily focussed, expanded, fiber coupled and manipulated by conventional optics to allow maximum flexibility for test and measurement applications. For example, in applications where more than one wavelength is required, a SuperK source together with a SpectraK Split or Dual allows the replacement of one to five lasers in a simple, compact, turn-key solution.
