This set of six precision-crafted glass lenses is ideal for exploring fundamental concepts in optics, including refraction, reflection, and focal length. Each lens is made from high-quality glass with ground and polished faces and edges, ensuring clarity and safety during handling. With a standard 50 mm diameter, these lenses are suitable for classroom demonstrations and student investigations, providing hands-on opportunities to understand the behaviour of light through different shapes and configurations.
The diverse range of lens types included in this set—double convex, plano convex, converging concave-convex, diverging concave-convex, double concave, and plano-concave—offers educators flexibility when teaching complex topics in physical science. They can be easily paired with ray boxes, laser pointers, or natural light sources for a variety of engaging experiments that demonstrate focal points, image formation, and lens behaviour.
Educational Benefits:
- Supports investigation of light behaviour through lenses.
- Promotes understanding of refraction, convergence, divergence, and focal points.
- Reinforces the scientific method through observation, hypothesis, and experimentation.
- Enhances practical skills in handling laboratory glassware and conducting optical tests.
Classroom Ideas:
- Use with a ray box to trace light paths through different lenses on paper.
- Compare converging and diverging lenses in image formation activities.
- Build simple telescopes or magnifiers using combinations of lenses.
- Explore how lens shape affects focal length using measured light paths.
- Integrate into STEM projects involving camera, microscope or projector simulations.
