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.
