Changzhou Ricun Optical Technology Co., Ltd

Changzhou Ricun Optical Technology Co., Ltd is based in China and lists sapphire crystal windows on Global Trade Plaza. The product is described for non-ornamental applications such as infrared optical components in scientific instruments, high-durability windows, and movement bearings, with the material noted as the third hardest mineral after diamond and moissanite. Features include high abrasion resistance, transparency from ultraviolet to infrared (0.15–5.5 µm), chemical and heat resistance up to 2000 °C, and suitability for electrical insulation. Stated applications cover UV and IR optics, high-temperature and high-pressure windows, heat sinks, semiconductor wafer carriers, electrical insulators, thin film deposition, transparent electronic substrates, and silicon-on-sapphire or superconductor substrates. Buyers can send an enquiry through Global Trade Plaza.
