    Customized BK7 B270 Optical Glass Convex Dome Lens For Smart Devices



    1. Glass Material:

      • N-BK7 & B270 Crown Glass:

        • N-BK7: Borosilicate crown glass with high transmission (350–2000 nm), low dispersion, and excellent thermal stability.

        • B270: Soda-lime crown glass with similar optical clarity (380–2500 nm), often used for cost-effective precision optics. Both materials prioritize homogeneity and low bubble/inclusion content.

    2. Key Properties:

      • Dome Geometry: Convex curvature provides wide-angle light collection, minimizes spherical aberration, and protects underlying optics.

      • High Transmission: >90% light transmission in visible spectrum (400–700 nm) for BK7; B270 offers comparable clarity.

      • Thermal Resilience:

        • BK7: Low thermal expansion (3.3 × 10⁻⁶/K).

        • B270: Moderate thermal stability (8.5 × 10⁻⁶/K), suitable for controlled environments.

      • Surface Quality: Precision-polished surfaces (scratch-dig: 40-20 or better) reduce scatter and distortion.

      • Durability: Resists humidity, mild acids, and mechanical wear.

    3. Primary Functions:

      • Focuses or collimates light in wide-angle optical systems.

      • Enhances light collection efficiency in imaging and sensing applications.

      • Protects sensitive components (e.g., sensors, LEDs) from environmental damage.

      • Corrects aberrations in compact optical assemblies.

    4. Applications:

      • Imaging Systems: Surveillance cameras, drone optics, and fisheye lenses.

      • Lighting: LED collimation, automotive headlights, and stage lighting.

      • Sensors: LiDAR, motion detectors, and industrial inspection systems.

      • Medical Devices: Endoscope tips, dermatology tools, and diagnostic sensors.

      • Aerospace/Defense: Missile domes, cockpit displays, and thermal imaging windows.

      • Advantages Over Alternatives:

        • BK7: Superior thermal/chemical resistance vs. B270.

        • B270: Cost-effective for non-extreme environments.

        • Dome shape reduces need for additional protective optics.

    5. Target Industries:

      • Consumer electronics (cameras, smart devices).

      • Automotive and aerospace engineering.

      • Industrial automation and robotics.

      • Medical technology and defense.
