"IHU250H" is a moldable ultraviolet-transmitting glass that can be processed at lower temperature ranges compared to quartz and has a thermal expansion rate close to that of metals.
Product Introduction: IHU250H The "IHU250H" is a glass that functions as an optical glass filter that transmits ultraviolet light, while also being usable as a molding material. Its lower processing temperature compared to quartz and thermal expansion rate closer to that of metals make it suitable for metallization. For detailed optical properties, please refer to the downloadable materials. Features ■ Processing temperature range is lower than that of quartz (1600-1700°C) (IHU250H: 563°C) ■ Thermal expansion rate is closer to that of metals than quartz, making it suitable for metallization ■ Available for sale as molding materials such as block materials, rod materials, and ball lenses.
