8" 0.3μm Cerium Oxide Lapping Film Disc – No Backing – Precision Optical Polishing

Cerium Oxide Lapping Film Discs are engineered for final-stage precision polishing of optical connectors, gemstones, glass, and ultra-precision optical components. Utilizing nanometer-grade 0.3μm cerium oxide powder bonded to durable polyester film, these discs deliver exceptional mirror surface finishes with superior consistency and long service life.

Key Features & Recommendations:

• Superior Polishing Finish: Ultra-fine 0.3μm cerium oxide particles deliver scratch-free, high-luster optical clarity on glass, quartz, and gemstones.

• Durable Polyester Backing: Plain backing (no adhesive) allows flexible mounting on standard master laps, backing plates, or magnetic discs.

• Wet Polishing Compatibility: Excellent water and coolant resistance prevents premature degradation during wet operations.

Applications:

• Lapidary & Gemstones: Final optical polish on quartz, agate, opal, glass, and softer gemstones.

• Optoelectronics & Fiber Optics: Precision finishing of fiber optic connectors and laser components.

• Metallography & Wafers: Defect-free surface preparation for microscopic analysis.
