Neste vídeo fascinante, acompanhamos o processo tradicional de fabricação e polimento de lentes ópticas de vidro: Fixação com Piche: As lentes brutas recebem marcações de grau e são coladas em suportes metálicos com resina aquecida. Esmerilhamento Curvo: A lente é pressionada contra um molde giratório com água e pó abrasivo para esculpir a curvatura exata da dioptria. Polimento de Precisão: Após ficar levemente fosca pelo atrito, a lente é polida repetidamente até atingir a transparência ópti
