Double-Convex Glass Lens – 75 mm Diameter, 20 cm (200mm) Focal Length
Bring the principles of light and optics into clear focus with this double-convex glass lens, a classic tool for homeschool and classroom physics experiments. With its symmetrical curved surfaces, the lens converges incoming light rays to a focal point, making it ideal for demonstrations involving magnification, image formation, and focal length measurement.
Students can use the lens to investigate how light bends through transparent materials, project images onto screens, or explore the relationship between distance, focus, and magnification. Its large 75 mm diameter provides a generous viewing area that makes experiments easy to observe during classroom demonstrations or small-group investigations.
