Customized BK7 B270 Optical Glass Convex Dome Lens For Smart
Devices
Glass Material: 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.
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.
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.
Target Industries: Consumer electronics (cameras, smart devices). Automotive and aerospace engineering. Industrial automation and robotics. Medical technology and defense.
