UV/VIS/NIR SPECTROSCOPY PERFECTION IN DETAIL DECISIVE STRENGTHS OF HELLMA ANALYTICS CELLS Cuvettes are not all the same, even if they sometimes appear identical. The difference lies in the details and can be crucial for measurement results. Take our cuvette windows, for example, which boast outstanding quality and a flatness tolerance of better than 0.001 mm (1 μm). The parallelism of both window surfaces relative to one another is just as important. Our high-precision production guarantees that the frontal deformation of the light wave passing through a cuvette window is less than 4...
