Latest Patents
One of Nakamura's latest patents is for a base body of a reflecting mirror and the method for preparing the same. This invention proposes a lightweight base body made from fused silica glass or high-silica glass, which offers excellent thermal and mechanical stability. The design includes a front plate that serves as the optical surface and a supporting body made of porous foamed glass, which is integrally bonded to the front plate. The bonding process involves sandwiching a layer of finely divided silica powder between the two parts and heating the assemblage to a temperature above the softening point of the silica powder. This method ensures a firm join between the components. Additionally, the mechanical stability of the base body can be enhanced by incorporating a rear plate and a reinforcing hoop-like side layer, both made from fused quartz glass or high-silica glass.
