The laser output is designed to remain within Class 1 laser safety limits under all reasonably foreseeable conditions including single faults, in compliance with IEC 60825-1:2014 (third edition). The laser output will remain within Class 1 limits as long as STMicroelectronics recommended device settings are used and the operating conditions, specified in the STM32L4 Series datasheets, are respected. The laser output power must not be increased by any means and no optics should be used with the intention of focusing the laser beam. Figure 1 shows the warning label for Class 1 laser products.
