Complete experiments This kit enables a range of imaging and standard optical routine experiments, making it suitable for handson exploration of fundamental optics topics. First choices for teaching Ideal for teachers, home learners, schools, and scientists seeking a reliable optical set for instructional use and practical demonstrations. Applications Widely used in middle and school physics laboratories to support practical optics activities and curriculum experiments. Fivepiece optical set Triangular prism; convex lens; concave lens; convex lens; concave lens. Practical use scenarios Classroom demonstration: use the triangular prism and lenses to illustrate light refraction, dispersion, and basic imaging concepts in a guided lesson. Studentled experiments: combine convex and concave lenses to explore image formation, focal length, and lens behavior in handson projects. Curriculum support: employ the kit alongside other optics equipment in middle and school physics labs to perform multiple standard optics experiments.
