Precision Polished N-BK7 Optical Lens with Custom BBAR Coating for Camera Modules

1. Core Product & Premium Material

• Product Identity: "Optical Lens" is the fundamental component, crucial for all imaging systems.

• Material Specification: "N-BK7" is a critical keyword. It denotes a specific, high-quality grade of borosilicate crown glass ("N" indicating a finer quality standard than standard BK7), known for its exceptional homogeneity, low bubbles/inclusions, and consistent refractive index. This targets buyers with stringent material requirements.

2. Key Manufacturing Property & Performance Enhancement

• Lead Property (Precision Polished): This signifies superior surface quality, typically implying low surface roughness and tight tolerances on curvature (e.g., λ/4 or λ/10 surface accuracy). This is non-negotiable for achieving high-resolution, low-aberration images in camera modules.

• Advanced Coating Feature: "with Custom BBAR Coating" is a major value proposition. "BBAR" (Broadband Anti-Reflection) coating is engineered to minimize reflections across the entire visible spectrum (and often beyond). "Custom" indicates the coating can be optimized for specific wavelengths or angles of incidence, maximizing light transmission and contrast for a particular camera sensor.

3. Defined Function & Target Application

• Primary Function: The lens is designed to focus light precisely onto an image sensor. The combination of precision polish and BBAR coating ensures minimal light loss (ghosting, flare) and high-fidelity image capture.

• Targeted Application: "for Camera Modules" is the precise application lock. This directly targets the massive industry manufacturing compact camera units for:

  • Mobile Phones and Tablets

  • Automotive (ADAS, dashcams)

  • Security and Surveillance

  • Medical Endoscopes

  • Machine Vision Systems
