Sector-Shaped Precision Optical Diffuser
Our series of optical diffusers is engineered using high-transmittance substrates such as White glass, EXG, and B270, specifically designed for optical systems with stringent light quality requirements. Through precision surface treatment, these diffusers achieve uniform wide-angle scattering while strictly controlling physical defects. The product line supports various complex geometric shapes, including sector/segments, as shown in the provided samples, ensuring industrial-grade reliability and optimal light efficiency.

Product Features
- Multi-Substrate Support: A variety of materials are available, such as high-performance EXG, CG (Corning), and B270, to meet different requirements for light transmittance and stability.
- Refined Visual Quality: Features a uniform translucent matte that ensures highly consistent scattering and effectively hides source structures (e.g., LED hotspots).
- Rigorous Defect Control: Strictly complies with industrial standards for scratches, pits, and edge chipping to prevent stray light interference.
- Advanced Geometric Processing: Utilizes precision CNC cutting to maintain superior edge quality, making it ideal for non-standard mounting positions.
Detailed Description
Material & Application Advantages:
- B270 / White glass: Offers high visible light transmittance, making it suitable for general illumination homogenization and commercial display applications.
- EXG / CG Materials: Known for exceptional chemical durability and thermal stability with ultra-pure substrates. These are the preferred choice for precision displays, medical diagnostics, and semiconductor equipment.
- Manufacturing Excellence: We prioritize physical precision alongside optical performance. By optimizing grinding and cutting processes, we limit edge chipping to under 0.3 mm, ensuring high mechanical strength and visual integrity during assembly. Furthermore, strict limits on scratches (< 0.06 mm) and pits (< 0.4 mm) ensure that the diffuser minimizes stray light even under direct, intense light sources.
Key Applications:
- High-end Lighting & Backlighting: Eliminates LED “granularity” to provide a pure area light source.
- Automated Inspection: Light path shaping for machine vision systems.
- Precision Instruments: Uniform illumination for endoscopes and spectral analyzers.
Customization Capabilities
- Shape Customization: Circular, Rectangular, Sector/Segment, and Stepped profiles.
- Thickness Range: 0.4 mm / 0.7 mm / 1.1 mm / 2.0 mm and other custom specifications.
- Surface Treatment: Single-sided or double-sided diffusion; optional AR (Anti-Reflective) coating to maximize light output.
