  • Glass Material:

    • Borosilicate BK7 (N-BK7): A low-dispersion crown glass composed of SiO₂ (70%) and B₂O₃ (10%), prized for high transparency (350–2000 nm wavelength range), exceptional homogeneity, and thermal resilience. Industry-standard for precision optics.

  • Key Properties:

    • Hemispheric Geometry: Half-sphere shape (flat base + convex dome) enables efficient light focusing, collimation, or coupling in compact designs.

    • Customizable Dimensions: Tailored diameters (1–30 mm) and radii of curvature for application-specific needs.

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

    • Thermal Stability: Low thermal expansion (3.3 × 10⁻⁶/K) ensures performance in fluctuating temperatures.

    • Optional Coatings: Broadband anti-reflective (BBAR), UV/IR, or laser-line coatings to enhance transmission (up to 99.5%) and reduce losses.

  • Primary Functions:

    • Focuses or collimates light in fiber-optic systems, lasers, and sensors.

    • Couples light between optical fibers, waveguides, or detectors.

    • Enhances numerical aperture (NA) in imaging and illumination setups.

    • Corrects spherical aberrations in compact optical assemblies.

  • Applications:

    • Fiber Optics: Fiber coupling, telecom transceivers, and end-face collimation.

    • Laser Systems: Beam shaping in diode lasers, medical lasers, and Lidar.

    • Biomedical Devices: Endoscopy, microscopy, and optical coherence tomography (OCT).

    • Sensors: Industrial inspection, spectroscopy, and environmental monitoring.

    • Consumer Electronics: Miniaturized optics for cameras, VR/AR lenses.

  • Technical Specifications:

    • Diameter: 1–30 mm (customizable).

    • Radius Tolerance: ±0.02 mm for precision alignment.

    • Coating Options: BBAR (400–700 nm), UV (250–400 nm), or IR (700–2000 nm).

  • Advantages Over Alternatives:

    • BK7 offers superior cost-effectiveness vs. fused silica or sapphire for visible/NIR applications.

    • Hemispheric design simplifies integration in space-constrained systems.

    • Customization ensures compatibility with niche optical setups.

  • Target Industries:

    • Telecommunications and photonics.

    • Medical device manufacturing.

    • Industrial laser systems.

    • Aerospace and defense (sensors, targeting).
