Laser distance meter works by emitting a laser beam to the target object, then receiving the reflected laser beam, and calculating the laser round trip time. This equipment generally use laser wavelengths in the visible range or near-infrared range, and these wavelengths have different requirements for eye safety.
Laser safety level
The safety of a laser distance meter is closely related to its laser rating. Lasers are divided into different categories according to their safety levels, from Level 1 to Level 4. Common laser distance meters are usually Class 1 or 2 laser products:
– Class 1 Laser: Considered safe and generally does not cause eye damage under normal use.
– Class 2 laser: Short-term direct exposure may cause some damage to the eyes, but under normal use conditions, eyes will not be significantly affected.
Safety precautions for using laser distance meter
1. Avoid looking directly into the laser beam: Although most laser distance meters are Class 1 or 2 lasers, direct line of sight contact with the laser beam may still cause eye damage. Avoid shining the laser beam directly into your eyes during operation, especially in strong light environments.
2. Maintain the normal use of the equipment: Follow the operating instructions provided by the manufacturer to ensure the normal use of the laser distance meter. Do not measure people or animals.
3. Protective measures: During the measurement process, you can wear appropriate laser protective glasses, especially when using high-power laser equipment or when you are not familiar with the performance of the equipment.
4. Regularly check the equipment: Regularly check the laser emitting part and other components of the equipment to ensure that they are in good working condition and prevent safety issues caused by equipment failure.
Overall, laser distance meter is relatively safe when used correctly. Understanding its laser grade and correct operating procedures are key to ensuring safe use. Users should follow relevant safety precautions when using laser distance meter to avoid unnecessary risks. Potential safety hazards in the use of laser distance meter can be minimized through appropriate protective measures and good operating habits.
