Optical Glass Wide-Angle Convex and Concave Optical Lens For Optics
Material Composition
Optical glass wide-angle convex and concave lenses are
precision-engineered from high-quality optical glass, such as
borosilicate crown (BK7) or fused silica. These materials are
chosen for their exceptional transparency, low dispersion, and
thermal stability. Advanced coatings, like anti-reflective (AR) or
scratch-resistant layers, are often applied to enhance performance.
Key Properties
High Refractive Index: Enables efficient light bending, critical for wide-angle applications.
Low Chromatic Aberration: Minimizes color distortion for clear imaging.
Durability: Resistant to thermal expansion, mechanical stress, and environmental degradation.
Wide Field of View (FOV): Convex lenses focus light to expand FOV, while concave lenses diverge light to correct spherical aberrations.
Functional Roles
Convex Lenses: Curve outward to converge light rays, magnifying images and capturing broader scenes. Ideal for wide-angle photography and surveillance.
Concave Lenses: Curve inward to diverge light, compensating for distortions (e.g., barrel distortion) in optical systems.
Combined Use: Integrating both lens types optimizes image clarity, reduces edge distortion, and balances light distribution in complex optical setups.
Applications
Photography & Videography: DSLR cameras, drones, and action cameras use wide-angle convex lenses for panoramic shots.
Scientific Instruments: Microscopes, telescopes, and spectrometers leverage concave lenses for aberration correction.
Medical Devices: Endoscopes and ophthalmic tools rely on compact wide-angle optics for precision imaging.
Automotive & Aerospace: LiDAR systems and dashboard cameras employ these lenses for enhanced spatial awareness.
Consumer Electronics: Smartphone cameras, VR headsets, and security systems utilize wide-angle optics for immersive experiences.
