  • Publication number: 20250230936
    Abstract: A protective barrier affixable to a curved substrate comprises a stack of two or more lenses, each of the two or more lenses including a polyethylene terephthalate (PET) film, a hard coat on a first side of the PET film, and an adhesive layer on a second side of the PET film opposite the first side. The stack of two or more lenses may have a modulation transfer function that exhibits a contrast value greater than 75% for a spatial resolution of one line-pair per 0.0003 radians at 65 degrees angle of incidence. Heat and pressure may be applied to conform the stack of two or more lenses to the shape of the curved substrate.

  • Patent number: 12358266
    Abstract: A method of manufacturing a polymer film includes melting a resin, extruding the melted resin through a die to produce a polymer film, shaping the polymer film, cooling the polymer film, illuminating a surface with a light source, capturing an image of a shadow cast by the polymer film on the surface while the polymer film is between the light source and the surface, calculating a frequency spectrum of at least a portion of the captured image, and adjusting a process parameter of the melting, the extruding, the shaping, or the cooling based on the frequency spectrum.

  • Patent number: 12330483
    Abstract: A protective barrier is affixable to a curved substrate such as a vehicle windshield. The protective barrier may include a stack of three or more lenses. Each of the three or more lenses may include a thermoplastic film (preferably a polyethylene terephthalate (PET) film) and an adhesive layer on a first side of the thermoplastic film. The three or more lenses may have respective thicknesses that define a monotonically decreasing function in a stacking direction of the stack and that include at least three different thicknesses. The protective barrier may be placed on the curved substrate with the adhesive layer of an innermost lens of the stack in contact with the curved substrate, and heat and pressure may be applied to conform the stack to the shape of the curved substrate. Thereafter, an outermost lens of the stack may be peeled off to reveal the next lens of the stack.

  • Publication number: 20240381968
    Abstract: An eye protector includes a lens configured to protect the wearer from projectiles, and an optically clear stack attached to the lens. The stack can have one or more removable layers. The eye protector also includes an optically clear dry mount adhesive layer attaching the stack to the lens. The dry mount adhesive may be self-wetting to attach the stack to the lens so that air between the stack and the lens can be removed after the stack is attached and/or adhered to the lens, for example, by applying pressure across the surface of the stack. The refractive indices of the lens, the dry mount adhesive, and each removable layer are matched to within about 0.2.

  • Publication number: 20240385352
    Abstract: Manufacturing a pre-molded stack of one or more lenses to be installable on a curved substrate such as a vehicle windshield includes placing a moldable stack of one or more lenses and adhesive layer(s) on a mold, applying heat and pressure to the moldable stack to produce a pre-molded stack of one or more lenses from the moldable stack, and removing the pre-molded stack from the mold. The pre-molded stack may have a compound curvature, which may match a curvature of the curved substrate. The mold may be formed using three-dimensional shape data derived from the curved substrate, such as by optically scanning the curved substrate.
