Empowering Key Industries with High-Purity Quartz

Our quartz solutions are engineered to meet the specific challenges of thermal, optical, and chemical environments.

Semiconductor Manufacturing

High-purity quartz chamber windows, pedestals, and shadow rings for Etch and CVD equipment. Critical for maintaining vacuum integrity and wafer purity.

Solar & Photovoltaic

Durable quartz cover plates and substrates for PV cell manufacturing. Withstands extreme thermal shock and chemical cleaning processes.

Optics, Laser & Medical

UV/IR optical windows, laser debris shields, and filters. High transmission (185-2500nm) and low defect density for precision laser and medical instruments.

Heating & Chemical Industry

High-temperature sight glass and observation windows for industrial furnaces and reactors. Excellent resistance to acid corrosion and high pressure.

Quality Assurance & Safe Delivery Guarantee

We understand that for quartz glass, precision and safety are paramount. Every shipment undergoes a rigorous 2-step verification process before leaving our factory.

Strict Quality Inspection (OQC) : Surface Quality check (40/20 Scratch-Dig), Flatness inspection (< 1λ), and strict dimensional tolerance (±0.05mm).

Shockproof Export Packaging : Anti-scratch protection: Individual vacuum packing or condenser paper interleaving between plates + reinforced wooden crate.

Global Logistics : Partnerships with FedEx/DHL for samples and reliable sea freight for bulk orders.
