Laser Pointers for Difraction and Interference Labs

My students need 6 laser pointers so that each of my physics lab teams can perform diffraction and interference experiments.

I have about 100 physics students in five classes: one AP class, three honors classes and one college preparation class. My students are a mix of disadvantaged and middle income students.

The cost of most optics equipment is prohibitively high for our school district, so we have had limited hands-on labs in optics. While we already have some simple equipment like prisms and diffraction gratings, we do not have a scientific light source. These laser pointers would rectify this situation by providing a coherent light source at a single frequency.

My students need 6 laser pointers so that each of my physics lab teams can perform diffraction and interference experiments. It is necessary to have the coherent light of a laser to properly perform these labs. With a set of lasers we can set up our lab teams to perform a variety of useful optics labs in diffraction and interference. For example, students will be able to use the laser light to measure the angles in which light bends in different materials to measure their indicies of refraction and determine their compositions. Students will also be able to measure the dispersion of light through diffraction gratings to determine the light frequencies of the lasers.

Optics is an important area of physics and engineering that is critical to American technology competitiveness in the global economy. Thank you for your assistance!
