Which statement about the laser devices is correct?

• A. The Laser Range Finder is Class 1; The Laser Pointer is Class 3B
• B. The Laser Range Finder is Class 3B; The Laser Pointer is Class 1
• C. The Laser Range Finder is Class 1; The Laser Pointer is Class 2
• D. The Laser Range Finder is Class 2; The Laser Pointer is Class 3B

Answer: (A)

Understanding laser safety classifications is about how much light energy a device can emit without posing a hazard to the eyes or skin during normal use. Class 1 means the device is safe as used, with emissions that stay within permissible exposure limits and any beam exposure being effectively inaccessible or attenuated. A laser range finder is designed to measure distance while keeping the user safe, usually with the laser housed and limited so that even accidental exposure stays below dangerous levels. That’s why it’s classified as Class 1.

A laser pointer, on the other hand, is intended to project a visible beam for pointing. If its output is high enough to be hazardous to the eye, it falls into Class 3B, which indicates a direct-eye hazard and requires precautions to prevent shining into eyes. This higher-risk classification is why the pointer is Class 3B.

So, the combination of a Class 1 laser range finder and a Class 3B laser pointer aligns with how these devices are typically designed and used, making that statement the correct one.
