High refractive index glass materials
WebJun 15, 2024 · For example, a standard plastic lens (with a refractive index around 1.50) and a 1.67 high-index lens might have the same prescription, but the high-index lens could be up to 30% thinner. . Conventional plastic lenses have a refractive index that hovers around 1.50, whereas the refractive index of conventional glass lenses is approximately 1.52. WebMaterials with an Abbe number greater than 55 (less dispersive) are considered crown materials and those with an Abbe number less than 50 (more dispersive) are considered flint materials. The Abbe number for visible materials ranges from 20 - 80, while the Abbe number for IR materials ranges from 20 - 1000. Index Gradient
