1.1.2 Laser safety considerations
The VL53L8CX 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.
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.
