Scientists have developed a new spectroscopy technique that can spot glass imperfections. The method helps spot the subsurface structural changes of silica glass due to nanoscale wear and damage. Applications like electronic displays and vehicle windshields will benefit from this development.
Surface defects are the main reason behind glass not being as strong as steel. The researchers used hyperspectral near-field optical mapping to spot the glass imperfections. The method allowed them to study the glass defects at ultra-small scales, which was never possible in the past.
Glass scientists can use this technique to learn how glass non-uniformities occur and what’s the physics behind that. Such knowledge-based development or processing will help with glass product improvements – making the glass surface better or more perfect, more durable, mechanically and chemically. This technique may lead to new advancements in glass science. Scientists can significantly increase their fundamental understanding of glass science by observing nano surface damage over multicomponent glass materials using this technique.
