New family of UV-shielding glass invented


New family of UV-shielding glass invented Today’s Video of the Day from Penn State describes a new family of glass that will be ideal for designing low-thickness lenses.

The researchers added zinc oxide to germanosilicate glass to produce a material that has a high refractive index.

The samples also proved to be highly transparent and flexible with good UV-shielding properties. This means the glass could be used to form lenses for glasses or to make windows.

“The motivation for the study was the need for new glass compositions that have a high refractive index while still being processable at an industrial scale,” said Professor John Mauro. UV Protection Film can help to filter out one of the sources of fading; however due to the virtually clear appearance, it does not offer protection against the other causes of fading. UV Protection Film will reduce the amount of harmful UV rays that enter through a window, while also offering a thin layer of protection against broken glass.

Plexiglass Acrylic Sheet – UV Filtering Ultraviolet plexiglass sheet formulations reduce damaging UV light waves. Within the Ultraviolet Spectrum, UVB (short wavelength high frequency) & UVA (long wavelength low frequency) are the two types of UV light that most concern us.

The study is published in the Journal of Non-Crystalline Solids.
