Our production capabilities cover the complete spectrum from micro-sized precision balls to large industrial-grade components, meeting the stringent requirements of optical instruments, measurement devices, and advanced industrial equipment.
Why Choose Our Optical Glass Balls?
Our optical glass balls distinguish themselves through exceptional transparency and precise dimensional control. With light transmission rates exceeding 92%, our products ensure minimal optical distortion while maintaining excellent mechanical properties. The manufacturing process employs advanced grinding and polishing technologies that achieve surface roughness below Ra 0.01μm, critical for applications requiring minimal light scattering.
The production facility spans 18,000 square meters across two campuses, featuring 12 automated production lines with annual capacity reaching 4,000 tons. This scale enables us to maintain consistent quality while offering competitive pricing. Our quality management system is certified to ISO 9001, IATF 16949, ISO 14001, and ISO 45001 standards, ensuring compliance with international requirements for optical components.
Precision Manufacturing Capabilities
We produce optical glass balls in diameters ranging from 0.3mm to 100mm, covering the complete spectrum of application requirements. The precision grade spans G3 to G2000, with spherical deviation controlled within ±0.001mm for ultra-precision applications. Each production batch undergoes rigorous inspection using laser interferometry and roundness measurement equipment to verify dimensional accuracy.
The material selection includes borosilicate glass, fused silica, and other specialized optical glasses depending on specific application requirements. For applications demanding enhanced durability, we offer chemical strengthening processes that increase surface compressive stress by 3-5 times compared to standard glass. This treatment significantly improves resistance to scratching and impact damage without compromising optical clarity.
Surface Treatment Options
To meet diverse application requirements, we offer multiple surface treatment solutions:
- Polishing: Achieves mirror finish with surface roughness Ra ≤ 0.005μm for minimal light scattering
- Chemical strengthening: Enhances surface hardness to 7H pencil hardness while maintaining transparency
- Anti-reflective coating: Reduces surface reflection to below 0.5% for high-performance optical systems
- Hydrophobic coating: Provides water and oil repellency for outdoor applications
- Custom coatings: Tailored solutions for specific wavelength requirements

FAQ
What makes optical glass balls different from regular glass balls?
Optical glass balls are manufactured using specialized glass compositions with extremely low impurity levels to ensure high light transmission and minimal optical distortion. The production process employs precision grinding and polishing techniques to achieve surface roughness below Ra 0.01μm, critical for maintaining optical clarity. Additionally, optical glass balls undergo strict quality control including interference microscopy inspection to verify dimensional accuracy and surface quality.
How do you ensure the dimensional accuracy of micro-sized glass balls?
For diameters below 1mm, we employ specialized production equipment including high-precision CNC grinding machines and laser measurement systems. The production process incorporates multiple quality checkpoints using optical comparators and laser interferometry to verify dimensions at each stage. For G3 grade precision balls (±0.001mm tolerance), we implement statistical process control (SPC) methods to maintain consistent quality across production batches.
What surface treatments are available for optical glass balls?
We offer several surface treatment options to enhance performance: 1) Polishing to achieve mirror finish with Ra ≤ 0.005μm; 2) Chemical strengthening to increase surface hardness to 7H pencil hardness; 3) Anti-reflective coating to reduce surface reflection below 0.5%; 4) Hydrophobic coating for water and oil repellency; 5) Custom band-pass coatings for specific wavelength requirements. Each treatment undergoes rigorous testing to verify performance characteristics before shipment.
