Translucent frosted quartz ring

The semi transparent frosted quartz ring is a customized quartz component designed specifically for high-precision processes and optical applications. Its unique semi transparent frosted surface effectively achieves uniform light scattering and surface anti slip, anti adhesion and other characteristics while maintaining the excellent physical and chemical properties of quartz. As a professional quartz product manufacturer, we provide global customers with customized services covering the entire process from material selection to precision machining.

Frequently Asked Questions (FAQ)

Q: What is the practical purpose of the frosted surface of the semi transparent frosted quartz ring?  

Answer: The frosted surface mainly achieves two functions: firstly, to diffuse the transmitted light and avoid direct local strong light, which is suitable for uniform light or shading scenes in optical equipment; The second is to increase surface friction to prevent sliding or adhesion caused by smoothness during assembly or use, and improve operational stability.

Q: How high temperature can this product withstand?  

Answer: Quartz material itself has excellent temperature resistance, with a long-term use temperature of over 1100 ℃ and even higher instantaneous temperature resistance. The specific temperature resistance performance depends on the actual usage environment and processing technology. We can recommend the most suitable quartz material grade based on your working conditions.

Q: Can non-standard sizes or irregular rings be customized?  

Answer: Sure. We support full parameter customization of outer diameter, inner diameter, thickness, frosted area, chamfer, opening, etc., with a minimum tolerance controlled within ± 0.05mm. Both standard circular rings and irregular structures with steps and positioning slots can be achieved.

Q: Will frosted surface affect cleanliness?  

Answer: Our sanding process has been optimized, and after surface treatment, it can undergo strict clean cleaning. Through ultrasonic cleaning and dust-free packaging, it meets the requirements of high cleanliness scenarios such as semiconductor and optical coating.

Application problems that the product can solve

In practical applications, customers often face the following problems:

-Uneven light intensity in the optical system: Ordinary transparent quartz rings will produce obvious light spots, affecting detection or exposure accuracy. The semi transparent frosted surface converts point light sources into uniform surface light sources, greatly improving the stability of the optical system.

-Component adhesion in high-temperature processes: In equipment such as PECVD and diffusion furnaces, quartz rings are prone to adhesion with wafers or carriers, leading to fragmentation or placement failures. The frosted surface reduces the contact area and effectively prevents high-temperature adhesion.

-Inaccurate positioning of automated production line: Smooth quartz rings are prone to slip or offset when grasped by robotic arms. The frosted surface increases the friction coefficient and improves the success rate of automated assembly.

-Long delivery time and high cost for imported parts: We provide customized alternative solutions that benchmark with imported quality, reducing delivery time by 30% -50% and making costs more competitive.

Customer Application Case (Anonymous)

Case 1: A semiconductor equipment manufacturer - Quartz rings for PECVD equipment

The customer originally used imported quartz rings, which had two major pain points: first, the quartz rings adhered to the ceramic carrier after high-temperature processing, making them prone to edge breakage during cleaning; Secondly, the delivery time is as long as 8 weeks, which affects the delivery of equipment.  

We have customized a semi transparent frosted quartz ring for it, with the frosted surface facing the ceramic carrier, effectively reducing contact thermal conductivity and adhesion force, and reducing adhesion problems by more than 90%. At the same time, through rapid sampling and material preparation mechanisms, the delivery time has been compressed to 3 weeks, helping customers shorten the overall delivery cycle. We have been supplying continuously for two years, with an annual purchase volume of over 2000 pieces.

Case 2: A certain optical testing equipment company - quartz rings for uniform light components

The customer requires a uniform light element with a diameter of 180mm, which requires a uniformity of illumination of ≥ 92% on the detection surface after the light passes through, and no bright rings at the edges. We use double-sided fine sanding technology, combined with thickness tolerance control within ± 0.03mm, to achieve a final uniformity of 95% and solve the problem of edge reflection. The customer replaced the original glass material scheme with a quartz frosted ring, significantly improving both temperature resistance and service life.

Case 3: A Photovoltaic Equipment Manufacturer - Anti slip Quartz Rings for Automated Transmission

When the customer's automated production line is transporting silicon wafers at high speed, the position drift between the silicon wafer and the quartz ring occurs due to insufficient friction coefficient, resulting in an increase in fragment rate. We have increased the friction coefficient by about 40% and reduced the fragmentation rate from 0.3% to below 0.05% by customizing the matte surface roughness Ra 1.2-1.8 μ m without affecting cleanliness, saving customers over one million yuan in costs annually.
