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.
