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 High Light Transmission: Achieves >99% transmittance (with AR coatings) across visible
to near-infrared spectra, minimizing energy loss. Low Thermal Expansion: Withstands temperature fluctuations (ΔT up to 300°C) without
deformation. Precision Surface Accuracy: λ/4 or better surface flatness ensures minimal wavefront
distortion. 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.
