Kohoku Kogyo Co. Ltd. has recently announced that it has developed a 0.5mm-thick product using SSG®? (slurry cast silica glass), a manufacturing technology for high-purity quartz glass products have successfully developed an ultra-thin quartz fly-eye lens.

SSG®? is characterized by having physical properties such as transmittance and purity equivalent to synthetic quartz. Synthetic quartz has superior corrosion resistance and heat resistance compared to general transparent glass, and is used in medical testing equipment, semiconductor manufacturing equipment, industrial products, etc.

On the other hand, synthetic quartz is a material that is difficult to be melted and molded at high temperatures, so machining and polishing are the main processing methods, making it extremely difficult to manufacture lenses in the shape of this project. The newly developed fly-eye lens takes advantage of the SSG®? manufacturing method, which allows molding at normal temperature and pressure, and further advances sintering technology to achieve a uniform thickness of 0.5 mm.

It is believed that this technology can contribute to improving the performance of equipment, measuring devices, etc., and to developing new products.
