This innovative System provides a reliable way to easily double-check laser safety calculations. It is based on the ANSI Z136.1 American National Standard for Safe Use of Lasers and will perform repeated calculations of maximum permissible exposure (MPE), optical density (OD), nominal ocular hazard distance (NOHD), nominal hazard zone (NHZ), and laser hazard classification.
