8 Laser safety considerations
The VL53L4CD contains a laser emitter and corresponding drive circuitry. 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 remains within Class 1 limits as long as STMicroelectronic’s recommended device settings are
used and the operating conditions specified are respected (particularly the maximum timing budget, as described
in the user manual .
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.
Caution: Use of controls or adjustments or performance of procedures other than those specified herein may result in
hazardous radiation exposure.
