During internal testing Leica Microsystems has become aware of a component change on the photodiodes inside the M530 Optics Carrier. The photodiodes are used as luxmeters to optimize the "brightcare plus" limit which is calculated based on real-time light intensity data to compensate for decreased light intensity as bulbs age. The component change of the photodiode will result in an inaccurate adjustment of the illumination limits. Recall start date: August 12, 2022
