Core Pain Points We Solve
Low-purity quartz contains bubbles and striae, causing light distortion for precision optical systems
Ordinary glass fails under high temperature and rapid thermal shock working conditions
Single material grade cannot cover deep UV, general UV and infrared multi-spectrum demands
Difficult to realize irregular shapes, drilling, grooving and customized optical coating
Key Features
Fully Customized Dimensions & Shapes
No fixed standard sizes. We cut quartz plates according to customer drawings, samples or parameter requirements, including irregular special outlines for unique equipment installation.
Ultra-High Optical Purity
Bubble-free and striae-free fused silica material ensures stable, distortion-free light transmission for precision optical systems.
Excellent Thermal Stability
Near-zero thermal expansion delivers strong thermal shock resistance, suitable for long-term operation under high and fluctuating temperatures.
Full Spectrum Light Transmission
Covers deep ultraviolet, visible light and mid-infrared bands to meet multi-band optical design demands.
Strong Chemical Inertness
Resist most acids, alkalis and organic solvents, perfect for chemical laboratories and corrosive industrial working environments.
Precision Custom Machining
Custom drilling, grooving and edge chamfering services, matched with optical-grade polishing to reach strict flatness and parallelism tolerances.
