Better tools for scientists
Klar Scientific is a startup specializing in spectroscopic microscopy using its patented confocal optical profile (COP) technology. The Klar approach is to integrate key functions in a portable instrument. The functions include photoluminescence (PL) and Raman spectroscopy, spectroscopic mapping, reflectivity, and topography.
A unique feature of the Klar microscope is the ability to provide a topographic map (surface profile) of the sample surface. While surface profilers exist commercially, they are not integrated with confocal microscopy and spectroscopy. This feature is especially useful for PL/Raman mapping because it will enable the microscope to maintain focus, even for rough or irregular surfaces. This feature is essential to optimize the spatial resolution.
