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