The polishing technology will determine the imaging and lens quality for some parts processing. In the field of precision optics, there are high requirements for surface accuracy and smoothness, and it achieves nanometer level standards, surpassing normal glass processing.
Mechanical polishing: Suitable for large components, low cost, but slow.
Magnetorheological polishing (MRF): Providing nanometer-level precision, capable of correcting complex curved surfaces, widely used in precision optical manufacturing.
Ion beam polishing (IBP): Providing atomic-level precision, suitable for extremely high-end optical applications, such as astronomical telescopes and EUV lithography equipment.
High-performance polishing powder is key to improving efficiency and surface quality:
Cerium Oxide (CeO₂): High cutting efficiency, a mainstream choice, suitable for most optical glasses.
Zirconium Oxide (ZrO₂): Higher hardness, suitable for soft glass such as FCD/FK series.
Full Particle Size Coverage: Large particle size powder (1–5μm) for rough polishing, submicron powder (0.1–1μm) for fine polishing, meeting the needs of different stages.
Excellent Performance: Stable suspension, low sedimentation, corrosion resistance, and easy cleaning ensure smooth subsequent coating processes.
