    BBAR AR Plano-Convex Optical Lens Optical Glass N-BK7 for Precision Aiming Optics

    1. Glass Material:

      • N-BK7 Optical Glass: A high-quality, low-dispersion borosilicate crown glass (SiO₂ + B₂O₃), widely used in precision optics due to its exceptional clarity, homogeneity, and thermal stability. Ideal for visible to near-infrared (350–2000 nm) applications.

    2. Key Properties:

      • Broadband Anti-Reflective (BBAR) Coating: Minimizes reflection losses (<0.5% per surface) across a wide spectral range (400–700 nm), enhancing light transmission (up to 99.5%) and image contrast.

      • Plano-Convex Design: Flat (plano) and convex surfaces enable collimated light focusing with minimal spherical aberration, critical for precision aiming systems.

      • Surface Quality: Precision-polished surfaces (scratch-dig: 40-20) ensure minimal scatter and distortion.

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

    3. Primary Functions:

      • Focuses collimated light into a precise spot or beam.

      • Corrects optical aberrations in aiming devices.

      • Enhances image resolution and targeting accuracy in low-light conditions.

    4. Applications:

      • Precision Aiming Optics: Rifle scopes, red dot sights, telescopic sights, and laser rangefinders.

      • Laser Systems: Beam collimation in industrial lasers and medical devices.

      • Imaging Systems: Microscopes, telescopes, and surveillance cameras.

      • Industrial Metrology: Alignment tools and precision measurement instruments.

    5. Technical Specifications:

      • Diameter: Customizable (common sizes: 5–50 mm).

      • Focal Length: Adjustable based on curvature.

      • Coating Durability: MIL-C-675C standard for scratch and environmental resistance.

    6. Advantages Over Alternatives:

      • Superior transmission and reduced glare compared to uncoated lenses.

      • N-BK7 offers better cost-performance balance than specialty glasses (e.g., fused silica).

    7. Target Industries:

      • Defense and military (firearm optics).

      • Hunting and sports optics.

      • Biomedical imaging and photonics.
