Stepped Quartz Plate | Custom Machined Quartz Components
Precision-machined Stepped Quartz Plates manufactured from high-purity fused silica (SiO2 ≥ 99.99%). Featuring multi-level structures and micron-level Z-axis accuracy for semiconductor, optical, and laboratory applications.
Product Overview
Our Stepped Quartz Plates are precisely machined to create multi-level structures according to functional and application requirements. These plates are widely used in laboratory instruments, semiconductor equipment, and optical assemblies where accurate height alignment, positioning, or specialized sealing is required.
We support custom production based on drawings or samples, including complex stepped geometries and tight tolerances.
