Latest Patents

James J Hagerty holds a notable patent titled "Glass Plate Fusion For Macro-Gradient Refractive Index Materials." This invention involves a glass block that consists of multiple intermediate glass plates stacked between a top plate and a bottom plate. The top and bottom plates are made of specific compositions that determine their index of refraction and softening temperature. The intermediate plates have compositions that are intermediate to those of the top and bottom plates, creating a gradient in composition from top to bottom. By heating the assembly at a fusion temperature, the plates are fused together to form a cohesive glass block. This innovative process allows for the creation of lenses with a gradient in the refractive index, achieving gradients of at least about 0.085, and potentially approaching 0.5. The thickness of the glass block can be substantial, with thicknesses of 10 mm and more being routinely achievable.
