Note: Nominal data represents typical values. Safety Advice: Laser bars are the active components in high-power Diode Lasers in accordance with IEC standard class 4 laser products. As delivered, laser bars cannot emit any laser beam. The laser beam can only be released if the bars are connected to a source of electrical energy. In this case, IEC-Standard 60825-1 describes the safety regulations to be taken to avoid personal injury
