Silicon/glass micromachined, fiber optics based, lab-on-chip device and metrological instrumentation for quality evaluation of animal oocytes by VIS/NIR transmission cell-by-cell measurement (400-950 nm) is shown. Several porcine and bovine oocytes were tested. 3 quality classes of porcine and 4 quality classes of bovines oocytes have been identified in a good agreement to classical veterinarian methodology.
