Optical Demonstration: This double convex lens has a 1.18 in diameter and 1.97 in focal length, making it suitable for showing refraction, focal points, and image formation in science education and lab experiments
Polished Glass Build: Made of polished optical glass with ground edges, this convex glass lens is designed for clearer viewing in classroom demonstrations and hands-on optics activities while keeping handling more controlled
STEM Learning Tool: the double convex lens helps students explore magnification, focal length, and image inversion through practical experiments, supporting classroom lessons, homeschool projects, and science kits
Edge-Finished Design: Each 30 mm optical lens features ground edges for smoother handling during demonstrations, making it easier to pass around in group settings, lab stations, and educational displays
6-Pack Supply: Includes 6 unmounted double convex glass lens pieces in one package, giving teachers, labs, and science programs a practical quantity for repeated experiments and multi-station use
