B270 BK7 Glass Optical Plano Lenses for Consumer Electronics
Core Substrate: Precision-cut optical-grade glass – B270® superwhite crown glass (cost-effective, high clarity) and BK7 borosilicate glass (superior homogeneity, low bubbles).
Coatings: Optional AR (Anti-Reflective), IR cut, or hard coatings for enhanced performance.
Surface Quality: λ/2 flatness tolerance, 60-40 scratch-dig standard (80-50 optional).
Transmission: >91% (B270) and >92% (BK7) across 400–700nm visible spectrum.
Thermal Stability: BK7: Low CTE (7.1 × 10⁻⁶/K); B270: Higher thermal expansion but lower cost.
Durability: Mohs hardness 6–7 (scratch-resistant), chemical-resistant surfaces.
Precision: Tight thickness (±0.02mm), diameter (±0.05mm), and parallelism (<5 arcmin) control.
Light Transmission: Maximizes undistorted light passage for sensors/displays.
Protective Barrier: Shields sensitive electronics from dust, moisture, and physical damage.
Beam Splitting/Filtering: Acts as substrate for coated optics (e.g., dichroic filters).
Optical Reference: Provides flat windows for interferometry or alignment.
Smartphones/Tablets:
Camera lens cover glass
Proximity/ambient light sensor windows
Fingerprint scanner covers
Wearables:
AR/VR headset lenses
