• OHARA SK1300 is a high‑quality optical glass substrate available in sizes ranging from 4 inches to 8 inches. Compared with conventional materials, this specialized glass features high purity and low hydroxyl (OH) content, making it suitable for semiconductor and liquid crystal display applications.
  • SK1300 offers excellent light transmission properties, especially in the ultraviolet and visible wavelength regions, with typical transmittance exceeding 90%. It possesses good mechanical strength, thermal resistance, and chemical durability. Its low dispersion and minimal birefringence make it an ideal choice for precision optical applications.
  • SK1310 is an anhydrous synthetic fused silica belonging to the SK‑1300 series. It retains the high reliability of SK1300 in terms of thermal resistance, mechanical strength, and chemical resistance.
  • Furthermore, since SK1310 contains no hydroxyl radicals, it exhibits no photolytic absorption at the 2.73 μm infrared wavelength. This product provides maximum transmission across the ultraviolet, visible, and infrared spectra.
  • Both SK1300 and SK1310 feature outstanding physical and chemical properties, enabling their wide application in advanced technology industries such as semiconductors and optics.
