The Laser Range Finder is a Class ____ laser.

• A. Class 1
• B. Class 2
• C. Class 3
• D. Class 3B

Answer: (A)

Laser safety classifications describe how much light energy can reach the eye. A Laser Range Finder is designed to be safe in normal use, so it falls into the lowest risk category. That means the emitted beam is kept within limits and often enclosed or otherwise engineered so that no hazardous exposure is possible during typical operation. In higher risk categories, direct viewing of the beam could injure the eye and protective measures or interlocks would be required. So the range finder is categorized as the safest option because its design ensures eye safety under normal use.
