INQUIRY

General Introduction: Ohara SK-1310 is the anhydrous synthetic fused silica among the SK-1310 series products of VAD-based synthetic fused silica.
In addition to the high reliability of heat resistance,mechanical strength,and chemical resistance maintained by SK-1310,photolytic absorption is not generated to the infrared area of 2.73 μm,because it doesn' t contain hydrogenous radicals.SK-1310 products are fully renovated materials with the maximum transmission applicable to the entire ultraviolet,visible,and infrared areas.
The physical and chemical characteristics are prominent similar to the SK-1310 products in a broad range of applications in advanced technological industries such as semiconductors and opticals.
