pointer is dangerous if one looks directly at the beam.
LIDAR is a pulsed fanning. A laser pointer is a focused beam.
Both class one, but the latter is dangerous.

Yes, class 1. It meets that, however, a simple class 1 laserOn Wed, 13 Jul 2022 16:41:47 -0700, John Larkin

You are determined to be both ignorant and offensive, and to
not say much about electronics.
He gave some good reasons pointing lasers at the public is a
bad idea most can be done better and safer with cameras.
The laser emission angle is 29 degrees, no worst than an LED.
If it\'s pulsed, I\'d expect the average optical power to be
microwatts. --

you are not correct
it doesn\'t matter pulsed or not,
laser beam should never been directed at eyes of people
Except that this is hardly a beam; it\'s a wide fan. Just because
it\'s a laser doesn\'t make it dangerous. Power density makes light
dangerous.
I don\'t think ST would sell it if it\'s dangerous.
Around here, we have swarms of Waymo cars that have spinning lidar
things all over them. I bet they are 1000x as powerful as that
tiny ST brick.

Once in a while we even see a giant thermonuclear light source in
the sky. I hear it can be dangerous to look at.
I bet that lidar unit meets the same eye safety requirements as
for an ordinary laser pointer or fiber optic IR communications
laser. Otherwise, ST would have to jump through impossible hoops.
Looked at the VL53L4CX datasheet. See Chapter 8 (Laser safety
considerations): IEC 60825-1:2014 (third edition). Meets Class I
safety, which means no restrictions, even without eye protection.
