Features


  • High Purity Composition: Contains 60–80% CeO₂ and 20–40% La₂O₃ for optimal polishing performance.

  • Controlled Particle Size: Median particle size (D50) of 1.8–2.4 µm ensures consistent and uniform polishing action.

  • Low Agglomeration: Narrow particle size distribution for reduced scratching and excellent surface smoothness.

  • Versatile Compatibility: Effective on a range of optical substrates including glass molds, resin lenses, and hard nitrates.

  • White Color: Clean finish with no residual staining—ideal for visible optical surfaces.

  • Multiple Packaging Options: Available in 20KG cartons and palletized options up to 960KG for both small-scale labs and industrial users.

Applications


  • Glass Mold Polishing: Ideal for precision polishing of complex optical mold surfaces.

  • Ophthalmic Lens Finishing: Smooth, scratch-free polishing of prescription and non-prescription lenses.

  • Optical Filter Polishing: Used for enhancing transmission and clarity in coated and uncoated optical filters.

  • Resin and Polycarbonate Lens Polishing: Effective on softer substrates used in consumer and industrial optics.

  • High-End Optical Components: Suitable for polishing prisms, laser optics, and photonic devices where surface quality is critical.

  • Hard Nitrate Material Finishing: Designed to handle harder substrates without compromising speed or surface integrity.
