Laser Safety

Laser Pointer

OSU’s Laser Safety Office and Laser Safety Committee oversee the use of Class 3B and Class 4 lasers on the OSU campus. As laser pointers are marketed and distributed as Class 2 or Class 3A lasers, they do not fall under the purview of the Laser Safety Office. However, recent studies suggest that some laser pointers are sold and marketed as lower Class 2 or Class 3A lasers, but they actually exceed the specifications for these classes and should rightfully be labeled class 3B lasers.

Please use discretion when using laser pointers and be aware of where the beam is directed. The documents and links below may provide some insight into the mislabeling and hazards associated with these seemingly harmless devices. Always contact the Laser Safety Officer if you have questions about the use of laser pointers.
