Laser safety considerations

The VL53L1X 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 the STMicroelectronics’

recommended device settings (driver settings) are used and the operating conditions

specified are respected.

The laser output remains within Class 1 limits as long as the STMicroelectronic’s

recommended device settings are used and the operating conditions specified are

respected (particularly the maximum timing budget, as described in the VL53L1X API user

manual UM2356).

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.
