High Precision CNC Machined Quartz Plates
High-precision CNC machined quartz plates are ultra-flat, dimensionally stable components made from fused silica (quartz glass), fabricated using advanced Computer Numerical Control (CNC) machining and grinding techniques. These plates offer exceptional thermal stability, optical clarity, and mechanical precision, making them ideal for demanding applications in semiconductor, optics, aerospace, and scientific research industries.
Key Features & Benefits
✔ Nanometer-Level Flatness – Achieves surface flatness down to λ/10 (≈63nm) for laser and optical applications.
✔ Extreme Thermal & Chemical Resistance – Withstands temperatures up to 1200°C without deformation; resistant to acids, plasmas, and harsh chemicals.
✔ Superior Optical Properties – High UV to IR transmission (≈90% from 185nm to 2.5µm) with minimal birefringence.
✔ Ultra-Low Thermal Expansion – Near-zero CTE (0.55 x 10⁻⁶/°C) ensures stability in fluctuating temperatures.
✔ Customizable Geometry – Precision-drilled holes, grooves, chamfers, and complex edge profiles with micron-level tolerances (±0.005mm).
Common Applications
Semiconductor & Wafer Processing – Mask aligners, lithography stages, etch chambers.
Laser & Optical Systems – Mirror substrates, beam splitters, interferometer plates.
Aerospace & Defense – IR windows, sensor protection, missile guidance components.
Medical & Biotechnology – Microfluidic chips, lab-on-a-disc devices, surgical tools.
Scientific Instruments – Vacuum viewports, particle detector mounts, synchrotron components.
Why Choose CNC Machined Quartz Plates?
Better than standard glass or ceramic plates – Higher purity, lower thermal distortion, and superior optical performance.
More durable than polymers – No degradation under UV, plasma, or high temperatures.
More precise than traditional machining – CNC ensures sub-micron accuracy for critical applications.
