When doing optics experiments, a method of securely holding optical elements is necessary. In school laboratories, optics experiments can be conducted using an optical breadboard or an optical bench. Alternative low-cost experimental kits have been proposed for optics experiments.1,2 For instance, the optical bench can be made from a plastic surface cable raceway (a cable conduit), and paper clips can be used to hold paper screens.1
This paper presents a continuation of the search for low-cost lab components, specifically optical boards and holders for optics experiments. A low-cost optical board can be simply made by using a magnetic rubber sheet and a clipboard. Steel binder clips can be used as holders and positioned anywhere on the optical board to create the experimental setup. Magnetic rubber sheets are widely available in online stores as well as local hardware stores, while clipboards and binder clips are commonly found in schools...
