This resource is a set of simple and low-cost lab manuals on the topic of optics, developed for high school and lower-level undergraduate level. The manuals provide detailed instructions for a broad overview of optics and photonics, including pinhole images, spectroscopy, reflection and refraction, a lens lab, and introductory labs in diffraction and polarization of light. Background information is given for each lab, plus diagrams/illustrations and data sheets for student use. This resource was sponsored by the NSF-funded Photon and Photon2 grants, awarded for the development of introductory curriculum on the topic of optics and light.
