Laser safety considerations
The
contains a laser emitter and the corresponding drive circuitry.
The laser output is designed to remain within Class 1 laser safety limits under all reasonable foreseeable
conditions, including single faults, in compliance with the IEC 60825-1:2014 (third edition).
The laser output remains within Class 1 limits as long as you use the STMicroelectronics recommended device
settings and respect the operating conditions specified in the data sheet.
The laser output power must not be increased and no optics should be used with the intention of focusing the
laser beam.
