Quartz Plates & Sheets

Our quartz plates, discs, and wafers are manufactured from high-purity 99.99% SiO2 fused quartz , also known as fused silica. These components offer excellent UV transmittance , particularly in the deep UV spectrum, and high optical transmission across a wide wavelength range. They exhibit exceptional high temperature resistance, suitable for continuous operation in applications up to 1200°C.

Our Process

Our quartz plates offer advanced fabrication capabilities, including laser drilling, slotting, and the production of high-precision, custom-shaped components.

Continuous Fusion Process for Quartz Plates

We utilize a continuous fusion process to produce high-quality quartz plates. This method ensures consistent material properties and efficient production of large-size sheets with excellent uniformity.

Waterjet Cutting

We use high-pressure waterjet cutting to shape quartz plates with precision and versatility. This cold-cutting process minimizes material stress and produces clean, chip-free edges, suitable for complex contours.

CNC Machining

Our CNC machining centers enable precision shaping, drilling, and milling of quartz plates. We achieve tight tolerances (down to 0.01mm) for features like pockets, steps, and custom contours.

Grinding (Various Techniques)

We offer a range of grinding services for quartz plates: single-side grinding for flatness, double-side grinding for parallelism and thickness control, and large-diameter cylindrical grinding.

Laser Drilling

We utilize laser drilling to create precise, micro-scale holes in quartz plates. This non-contact process offers excellent control over hole diameter, depth, and taper, with minimal heat-affected zone.

quartz plate FAQ

We offer various grades of quartz plates to meet different application requirements, including JGS1 (UV grade), JGS2 (Visible grade), JGS3 (Infrared grade), and custom grades with specific purity and optical properties. We can help you select the best grade for your needs.

Fused quartz has excellent thermal resistance. The continuous operating temperature is typically around 1100°C, with short-term use up to 1300°C possible. However, the actual maximum temperature depends on the application and environmental conditions.

The surface quality depends on the specific requirements. We can offer different surface finishes from commercial polish (around Ra 40-50 angstroms) to precision optical polish (Ra<5 angstroms).

Yes, we offer extensive customization capabilities. We can cut, grind, and polish quartz plates to your specific dimensions, shapes, and tolerances. We can also provide edge treatments, bevels, and holes.

We can achieve very tight tolerances, depending on the size and thickness of the plate. We can typically hold tolerances of ±0.01mm or better for precision applications. Please provide your specific requirements for a precise quote.

Yes, we offer a wide range of optical coatings, including anti-reflective (AR) coatings, high-reflection (HR) coatings, beamsplitter coatings, and filter coatings. We can customize the coating design to meet your specific spectral requirements.

The lead time depends on the complexity of the customization, the quantity, and our current production schedule. We will provide an estimated lead time with your quote.

We have a rigorous quality control system that includes incoming material inspection, in-process inspection, and final inspection. We use advanced metrology equipment to ensure dimensional accuracy, surface quality, and optical performance.

Yes, we can provide material certifications, including chemical composition analysis and purity reports. We can also provide inspection reports with dimensional measurements, surface quality data, and optical performance data.
