Fundamentals of Light and Lasers: Laser Eye Protection Equipment

This lab activity, presented by John Chamberlain, demonstrates the determination of the minimum optical density of protective eye equipment needed for working with lasers. In the six-minute video, Chamberlain uses the example helium neon laser to show the process of calculating this optical density and thus the needed filter for safety. This lab, 1-3B, is the ninth in a series of 20 available on the Fundamentals of Light and Lasers. 

These videos were created as a supplement to the Fundamentals of Light and Lasers curriculum available through OP-TEC, but can be used independently to guide lab activities related to this topic.
