Fundamentals of Light and Lasers: Optical Photometer Use and Stability

This lab activity, presented by John Chamberlain, demonstrates the use of a photometer. In this six-minute video, Chamberlain uses the photometer to take readings of the sun's light as well as a reading of a helium neon laser beam. This three-part lab, 1-3E, is one 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.
