What is the eye safe distance for the LRF?

• A. 15 meters
• B. 50 meters
• C. 25 meters
• D. 100 meters

Answer: (C)

Eye safety with a laser range finder centers on how much laser energy can reach the eye. The LRF is designed so that beyond a certain distance the energy reaching the eye stays below the maximum permissible exposure, making the beam effectively eye-safe. For this equipment, that boundary is 25 meters. Closer than that, there could be a risk if someone looks directly into the beam; farther away, the exposure stays within safe limits. That’s why 25 meters is the correct eye-safe distance.
