The SuperK GAUSS is a tunable Gaussian spectral filter that transforms the broadband output of a SuperK super-continuum laser to a Gaussian output with a wide band-width (depending on the center wavelength). The SuperK GAUSS is especially suited for Optical Coher-ence Tomography (OCT) and White Light Inteferometric (WLI) applications, where the Gaussian output(s) pro-vides clean artifact-free images with high resolution
