ZMSH specializes in custom-manufactured 3-inch quartz wafers, offering tailored solutions for advanced optoelectronic, MEMS, and semiconductor applications. Unlike standard 2-inch wafers, 3-inch quartz wafers provide expanded surface area for multi-component integration, enabling high-precision devices with enhanced performance. Key features include:
· Material: High-purity fused silica (SiO₂) with <50 ppm hydroxyl content, ensuring ultra-low optical loss.
· Dimensions: Custom diameters (3.00" ±0.02") and thicknesses (0.525–1.200 mm, TTV ≤10 μm).
· Shapes: Circular, square, or irregular geometries with non-standard apertures, stepped edges, or gradient thickness.
· Surface Finish: Ultra-smooth surfaces (Ra ≤1.0 nm) for minimal light scattering.
