Nippon Sheet Glass (NSG) and Olympus have together developed a technology to create microscopic irregularities on a glass surface in the order of 100nm to micrometers. The two companies will develop the technology for use in making optical products such as mirrors and cover glasses, micro reactors, biochips, and nano-input and plastic molding stamps, without using semiconductor processing and metal molding. The technology uses a sharp tool to locally apply high pressure on a glass surface to create condensed layers. On immersion in a hydrofluoric acid solution, irregularities are created on the glass surface as the locally condensed layers are etched at different rates. Olympus and NSG aim to market the products resulting from the new technology in two years“ time.
