In the global industrial manufacturing and scientific research fields, quartz plates have become an indispensable key material in semiconductors, photovoltaics, optical devices, and laboratory equipment due to their high purity, high temperature resistance, low thermal expansion coefficient, and excellent optical properties. However, the performance of quartz plates is highly dependent on their manufacturing accuracy - small deviations in dimensional tolerances, flatness, parallelism, and surface quality can all affect the overall efficiency of the system. Therefore, choosing a high-precision quartz plate factory is the foundation for ensuring the success of the project.

Luverre Quartz is a manufacturer focusing on producing various quartz plates, we can produce customized quartz plates in different sizes and shapes, such as square, round, oval and other special shaped designs according to customer's requirements.

Why is the accuracy of quartz plates crucial?

Quartz plates are widely used in:

-Semiconductor manufacturing: As a carrier substrate or window plate in lithography machines and diffusion furnaces, accuracy directly affects the yield of chip production.

-Optics and laser systems: used for optical lenses, mirrors, and filter substrates, precision deviations can cause optical path deviation or energy loss.

-Photovoltaic industry: In photovoltaic cell coating and testing equipment, high flatness quartz plates ensure process uniformity.

-Laboratory and medical equipment: used as high-temperature reaction vessels and spectrometer windows, requiring extremely high chemical purity and dimensional stability.

If the accuracy of the quartz plate is insufficient, it may lead to difficulties in equipment calibration, process fluctuations, increased product defect rates, and even cause production line downtime losses.

The core advantage of high-precision quartz plate

1. Micron level tolerance control: By using CNC precision machining and laser cutting technology, a dimensional tolerance of ± 0.01mm can be achieved, and the flatness can reach λ/10 (about 0.06 μ m).

2. Excellent thermal stability: High purity quartz sand (SiO ₂ ≥ 99.99%) is selected, with a thermal expansion coefficient as low as 5.5 × 10 ⁻⁷/℃, ensuring minimal deformation under temperature differences of -100 ℃ to 1200 ℃.

3. Customized surface treatment: Polishing, coating, drilling, chamfering and other processing can be provided according to needs, with a surface roughness of Ra ≤ 0.2 μ m, reducing scattering and energy loss.

4. Strict quality control system: Each batch of products is tested using laser interferometers, coordinate measuring machines, and spectral analysis to ensure traceability of performance parameters.
