{"product_id":"glass-lenses-50-mm-set-of-6","title":"Glass Lenses - 50 mm, Set of 6","description":"\u003cp\u003eThis 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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEducational Benefits:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eSupports investigation of light behaviour through lenses.\u003c\/li\u003e\n\u003cli\u003ePromotes understanding of refraction, convergence, divergence, and focal points.\u003c\/li\u003e\n\u003cli\u003eReinforces the scientific method through observation, hypothesis, and experimentation.\u003c\/li\u003e\n\u003cli\u003eEnhances practical skills in handling laboratory glassware and conducting optical tests.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eClassroom Ideas:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eUse with a ray box to trace light paths through different lenses on paper.\u003c\/li\u003e\n\u003cli\u003eCompare converging and diverging lenses in image formation activities.\u003c\/li\u003e\n\u003cli\u003eBuild simple telescopes or magnifiers using combinations of lenses.\u003c\/li\u003e\n\u003cli\u003eExplore how lens shape affects focal length using measured light paths.\u003c\/li\u003e\n\u003cli\u003eIntegrate into STEM projects involving camera, microscope or projector simulations.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eQuantity: Set of 6 lenses\u003c\/li\u003e\n\u003cli\u003eDiameter: 50 mm per lens\u003c\/li\u003e\n\u003cli\u003eLens types included:\u003c\/li\u003e\n\u003cli\u003eDouble convex\u003c\/li\u003e\n\u003cli\u003ePlano convex\u003c\/li\u003e\n\u003cli\u003eConverging concave-convex\u003c\/li\u003e\n\u003cli\u003eDiverging concave-convex\u003c\/li\u003e\n\u003cli\u003eDouble concave\u003c\/li\u003e\n\u003cli\u003ePlano-concave\u003c\/li\u003e\n\u003cli\u003eFocal lengths: 20 cm, 30 cm, and 50 cm\u003c\/li\u003e\n\u003cli\u003eFeatures: Ground and polished faces and edges\u003c\/li\u003e\n\u003cli\u003eSupplied in protective storage box\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Modern Teaching Aids NZ","offers":[{"title":"Default Title","offer_id":42238448107633,"sku":"EIS0538A","price":49.95,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/7633\/6753\/files\/eis0538a_glass-lenses-8211-set-of-6-8211-50mm-dia-in-box.webp?v=1768791761","url":"https:\/\/teaching.co.nz\/products\/glass-lenses-50-mm-set-of-6","provider":"Modern Teaching Aids NZ","version":"1.0","type":"link"}
