It is well-known that constant exposure to light through certain types of lasers and other light sources can cause permanent damage to the eyes. In some cases, certain high-power laser devices require appropriate eye and skin protection. Wondering if our laser distance sensors are considered eye-safe?

Lasers are divided into four classification groups, with Class 1 considered safe from all potential hazards, up to Class 4, which are high-powered devices that can result in severe damage to the eyes and the skin. See an overview of the laser classification system and class safety information below:

  • Class 1 – safe under all conditions of normal use
  • Class 2 – 0-1mW – safe due to the blink reflex
  • Class 3 – 1 – 500mW – moderate to serious eye hazard
  • Class 4 – 500mW+ – eye and skin hazard

Dimetix sensors belong to Laser Class 2. In this class, the risk of eye injury is low. These sensors, sold in the USA by Laser-View Technologies, have visible laser light and a laser power pulse <1mW, yet still measure distances up to 500m.

It should be acknowledged that in normal cases, the bright light of a Class 2 laser beam directed into the eyes will cause the blink reflex, or an instinctive reaction to look away or close the eyes. This automatic response is expected to protect you from laser damage to the eyes.

If Class 2 laser beams are directly viewed for a prolonged period of time, damage to the eyes could occur. Avoid looking into a Class 2 laser beam or pointing the beam into another person’s eyes. Avoid viewing Class 2 laser beams with telescopic devices.
