Its gentle curvature and precision-crafted optical glass enable learners to observe how even distant focal points can produce image clarity. Ideal for high-level optics demonstrations, it supports detailed learning about light paths and image projection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eEducational Benefits:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eEncourages understanding of advanced light refraction principles.\u003c\/li\u003e\n\u003cli\u003eDemonstrates how focal length influences optical instrument design.\u003c\/li\u003e\n\u003cli\u003eSupports student-led investigations in physical sciences.\u003c\/li\u003e\n\u003cli\u003eProvides opportunities for modelling lenses used in telescopes and cameras.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eClassroom Ideas::\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eIntegrate into telescope-building challenges for senior students.\u003c\/li\u003e\n\u003cli\u003eExamine the differences in focus sharpness using varied focal lengths.\u003c\/li\u003e\n\u003cli\u003eCompare beam width and convergence through multiple lenses.\u003c\/li\u003e\n\u003cli\u003eExplore image formation at different object distances.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLens type: Bi-convex\u003c\/li\u003e\n\u003cli\u003eDiameter: 50mm\u003c\/li\u003e\n\u003cli\u003eFocal length: 500mm\u003c\/li\u003e\n\u003cli\u003eMaterial: Ground-edge, polished optical glass\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Modern Teaching Aids NZ","offers":[{"title":"Default Title","offer_id":42238262607985,"sku":"EIS0534-L","price":6.15,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0626\/7633\/6753\/files\/eis0534-l_bi-convex-lens-50mm-fl-500mm.webp?v=1768791767","url":"https:\/\/teaching.co.nz\/products\/bi-convex-lens-50-mm-focal-length-500-mm","provider":"Modern Teaching Aids NZ","version":"1.0","type":"link"}
