主要功能
High Optical Transmission
Fused silica is recognized for its excellent optical performance across a broad wavelength range. Depending on the selected material grade, quartz wafers can provide outstanding transmission from deep ultraviolet to infrared wavelengths. This makes them suitable for optical windows, laser systems, imaging equipment, spectroscopy instruments, and photonic devices.
優異的熱穩定性
One of the most important advantages of quartz wafers is their extremely low coefficient of thermal expansion. This characteristic allows the material to maintain dimensional stability during temperature fluctuations and high-temperature processing. As a result, quartz wafers are widely used in semiconductor manufacturing, laboratory testing, and thermal processing applications where precision is critical.
Superior Chemical Resistance
Quartz wafers exhibit excellent resistance to most acids, solvents, and corrosive chemicals. This property allows them to perform reliably in harsh processing environments and chemical laboratories. Their chemical stability also reduces contamination risks in sensitive manufacturing processes.
High Purity Material
Manufactured from synthetic fused silica, these wafers offer extremely low impurity levels and excellent material consistency. High purity is essential for semiconductor, photonics, and precision optical applications where contamination can significantly affect product performance.
精密表面品質
Quartz wafers can be supplied with single-side polishing or double-side polishing to meet different application requirements. High-quality polished surfaces improve optical performance, coating adhesion, and overall process consistency.
Custom Manufacturing Capabilities
In addition to standard wafers, custom solutions are available, including special thicknesses, drilled holes, slots, edge profiling, laser cutting, and optical coatings. This flexibility enables customers to obtain substrates tailored to their specific designs and manufacturing processes.
