Index of refraction polycarbonate
Webindex number, the more a material will slow down and bend light. So less curvature is needed to create a given lens power. Poly has an index of refraction of 1.586. The index of Trivex is 1.530. Steeper curves would be needed to make an Rx in Trivex than in polycarbonate. The higher the lens power, the more difference there will be in curves ... WebPolycarbonate lenses possess a refractive index of 1 1.59, making them 20% to 25% thinner than regular plastic lenses. They are also up to 30% lighter than regular plastic material …

Les polymères sont des matériaux omniprésents dans la plupart des domaines scientifiques et d'ingénierie. L'indice de réfraction est une propriété d'importance dès lors que l'on utilise les plastiques pour des applications optiques. La faiblesse des plastiques « optiques » vient de la littérature inégale les concernant, souvent moins fournie que celle des verres optiques : les données sont de ce fait moins fournies, moins … WebFigure 1 shows light crossing from medium 1 (white) with refractive index n 1 to medium 2 (blue) with refractive index n 2 . The incident light is at an angle at the angle θ 1 to the normal. The light will be refracted to angle θ 2 in medium 2, where the relationship between θ 1 and θ 2 is given by:
Webdifficult. The high index of refraction also necessitates that good anti-reflection coatings be used. Germanium is quite expensive. 2.2 Silicon Silicon is a crystalline material like germanium. It is used primarily in the 3 μm to 5 μm MWIR spectral bands, because of absorption in the 8 μm to 14 μm LWIR band. The index of refraction
