Diffraction using a laser
 With the Altay Optics Upgrade 3 you will complete your advanced optics
experiments. Optics Upgrade 3 introduces further concepts of physical optics and
allows study in advanced optics. The diode laser allows you to study light as an
electromagnetic wave and introduces the concept of diffraction. As in Optics
Upgrade 2 all components are designed to work with the optical bench.
