APPARATUS FOR OPTICAL DETECTION OF BIO-CONTAMINANTS BASED UPON MEASUREMENT OF SATURATION OF LIGHT INTENSITIES AT FLUORESCENCE WAVELENGTH RELATIVE TO LIGHT INTENSITIES AT A PREDETERMINED WAVELENGTH

摘要

A method for optical detection of residual soil on articles (such as medical instruments and equipment), after completion of a washing or a rinsing operation by a washer. A soil detection system provides an indication of soil on the articles by detecting luminescent radiation emanating from the soil in the presence of ambient light.
