Applications

High-power industrial lasers require optical components with low absorption, high laser damage threshold (LIDT), and tight surface quality tolerances. JiuHongKe supplies UV fused silica windows, lenses, and mirrors for CO₂, Nd:YAG, UV, and fiber laser systems used in material processing, medical treatment, and precision marking.

Research-grade optical components require exceptional surface quality (10-5 S/D), tight flatness (λ/10), and precise wavelength-specific coatings. JiuHongKe works with university laboratories and instrument manufacturers to supply custom fused silica windows, prisms, beamsplitters and mirrors for spectrometers, interferometers, and laser experimental setups.

IGBT and SiC power semiconductor wafers are the core switching devices in modern power conversion systems. JiuHongKe supplies 1200V–3300V rated wafers with Ti/Ni/Ag multilayer metallization and precision dicing for EV motor controllers, on-board chargers, industrial inverters, and HVDC systems.

UV and deep-UV optical windows are critical components in wafer inspection and photolithography equipment. As a future expansion, JiuHongKe is developing supply capabilities for ArF (193nm) grade fused silica windows and optical elements for semiconductor process equipment.
