Glass Spherical Lenses are optical elements with symmetrical spherical surfaces made from materials such as BK7 or fused silica. They are designed for basic light focusing and imaging functions across visible and near-infrared wavelengths. These lenses are produced using standard grinding and polishing techniques, allowing efficient large-scale manufacturing. They are widely used in cameras, microscopes, laser modules, and machine vision systems. Their simple geometry provides predictable optical behavior, making them suitable for general-purpose optical applications where moderate precision is required.
