It is an ideal choice for high-end industrial lighting, medical lighting and precision optical systems.

Product Q&A (FAQ)

Q: How is the "wear-resistant" characteristic of this "wear-resistant fused silica rod" realized? How is it different from a regular quartz rod?

A: Although the ordinary fused silica rod has high hardness (Mohs hardness is about 6.7), it may still produce micro scratches or damage under specific friction or impact environment. Our wear-resistant photoconductive fused silica rods are enhanced by one or more of the following technical approaches:

Special surface treatment process: Advanced chemical mechanical polishing (CMP) or surface densification treatment is used to significantly improve surface smoothness (up to Ra0.2 μ m mirror effect) and surface density, reduce friction coefficient, and enhance scratch resistance.

Optimize material formula and melting process: By selecting high-purity raw materials (SiO ₂ content ≥ 99.5%) and controlling the crystallization tendency during the melting process, a more uniform and dense glassy structure is obtained, which enhances the material's ability to resist wear and microcrack propagation from the material itself.

Special coating (optional): Depending on specific application requirements, services can be provided to coat the surface of quartz rods with special wear-resistant, anti reflective, or protective coatings.

Q: As a light guiding rod, what are its main optical performance indicators? What is the transmittance that can be achieved?

A: As a light guiding rod, its core optical properties include:

High light transmittance: in visible and near-infrared bands, the light transmittance of high-quality fused silica can reach more than 90%, and some high-purity products can have more than 99% light transmittance at specific wavelengths.

Low color cast: Ensure the color fidelity of transmitted light, making the illuminated object appear natural colors.

Excellent light uniformity: Through precise manufacturing processes, the distribution of light within the rod is ensured to be uniform, avoiding dark areas or bright spots.

Customizable numerical aperture (NA): According to the requirements of optical coupling efficiency, it can be optimized by designing the core and cladding (for composite structures) or end face treatment.

Q: What other outstanding physical and chemical properties does it have besides wear resistance and optical conductivity?

A:

Excellent high temperature resistance: The softening point is as high as about 1730 ° C, and the long-term use temperature can reach over 1100 ° C, with the ability to withstand higher temperatures in the short term.

Extremely low coefficient of thermal expansion: about 0.55 × 10 ⁻⁶/° C (20 ° C), endowing it with excellent thermal shock resistance and the ability to withstand drastic temperature changes without cracking easily.

Excellent chemical stability: resistant to strong acids (except hydrofluoric acid and hot phosphoric acid), water-resistant, and resistant to corrosion by most chemical solvents.

Good electrical insulation: high resistivity, low dielectric loss.

High mechanical strength: With high compressive strength and wear-resistant properties, it is suitable for use in environments with certain mechanical stresses.

Q: What specifications and sizes of customized services can be provided?

A: We provide comprehensive customized services to meet the unique needs of different applications:

Diameter: It can be processed from a few millimeters to hundreds of millimeters.

Length: Customized according to customer needs, from short bars to long bars.

Customer Application Cases

Case 1: A well-known industrial automation equipment manufacturer (anonymous)

Application background: The customer is looking for a light guide rod for their new generation of online detection system for surface defects in automotive parts. This detection system requires 360 degree scanning of metal parts on a high-speed production line, and the end of the light guide rod needs to be very close to the moving part, which poses a risk of accidental scratching by the edge of the part.

Challenge: After several months of use, ordinary quartz optical rods may have fine scratches on their surface, causing light scattering and affecting detection accuracy. They need to be replaced frequently, which increases maintenance costs and downtime for customers.

Our solution: After in-depth communication with customers, we recommended our wear-resistant optical waveguide fused silica rod. By adopting a special surface densification treatment process, its surface hardness and scratch resistance have been significantly improved. At the same time, according to the customer's optical design requirements, products with specific diameters (Φ 8mm), lengths (150mm), and end face angles (45 ° polished) have been customized.

Application effect: After a year of continuous operation testing at the customer's site, the surface of the wear-resistant optical rod has no obvious scratches, and the shape and intensity of the light spot remain stable. The false alarm rate and missed alarm rate of the detection system have been significantly reduced. Customer feedback shows that the expected lifespan of the product can be extended by more than three times, greatly reducing maintenance costs and improving the overall efficiency of the production line.

Case 2: A high-end medical equipment research and development institution (anonymous)

Application background: The institution is developing a new type of portable endoscope for minimally invasive surgery. The guiding beam of an endoscope needs to transmit high brightness and high uniformity cold light within an extremely thin diameter, and the entire probe needs to be able to withstand repeated high-temperature and high-pressure sterilization.

Challenge: There are extremely high requirements for the diameter (within 3mm), flexibility (with certain bending), light transmittance, uniformity, and sterilization resistance of the light guide rod. Standard products on the market are difficult to fully meet their compact design and performance indicators.

Our solution: we use high-precision drawing and processing technology to customize a Φ 2.5mm ultra-fine wear-resistant photoconductive fused silica rod for customers. By optimizing the melting process, the high purity and excellent optical uniformity of the material have been ensured. Meanwhile, the chemical stability and high temperature resistance of quartz material itself enable it to easily cope with high-pressure sterilization environments. We also assisted the client in performing special polishing treatment on the end face of the light guide rod to optimize the optical coupling efficiency.

Application effect: The customized light guide rod is perfectly integrated into the customer's endoscope prototype, providing bright, uniform, and high color reproduction lighting effects. After hundreds of high-pressure sterilization cycles, the performance of the light guide rod has not deteriorated and its mechanical strength has not been affected.
