Detailed Product Description



Optical Grade Plano Convex Lenses for Beam Focusing & Magnification

Material Composition
These lenses are manufactured from high-purity optical-grade glass, such as BK7, N-BK7, or fused silica, chosen for their exceptional clarity and minimal impurities. Precision-ground and polished using advanced CNC machining, they feature a flat (plano) surface and a convex spherical surface. Optional anti-reflective (AR) coatings (e.g., MgF₂) are applied via vacuum deposition to enhance performance.

Key Properties

  1. High Light Transmission: Achieves >99% transmittance (with AR coatings) across visible to near-infrared spectra, minimizing energy loss.

  2. Low Thermal Expansion: Withstands temperature fluctuations (ΔT up to 300°C) without deformation.

  3. Precision Surface Accuracy: λ/4 or better surface flatness ensures minimal wavefront distortion.

  4. Low Dispersion: Reduces chromatic aberration for accurate color and beam fidelity.

Functional Benefits

  • Beam Focusing: The convex surface converges light into a tight focal point, ideal for collimating divergent beams in lasers or LEDs.

  • Magnification: Enlarges images in optical systems while maintaining sharpness and minimal distortion.

  • Durability: Scratch-resistant and chemically inert, outperforming plastic lenses in harsh environments.

  • Customizability: Available in diameters (5–300 mm), focal lengths, and coatings (UV/IR, broadband AR) for tailored solutions.

Applications

  • Laser Systems: Collimating laser diodes, fiber optic coupling, and laser engraving/cutting machines.

  • Imaging & Microscopy: Telescopes, microscopes, and projectors requiring high magnification and clarity.

  • Medical Devices: Endoscopic imaging, ophthalmic diagnostics, and surgical laser tools.

  • Industrial Automation: Barcode scanners, LiDAR, and optical sensors in robotics.

  • Scientific Research: Spectroscopy, beam expanders, and optical experiments demanding precision.
