hyper-hemispherical lens

The hemispherical lens effectively enhances the numerical aperture of optical systems through its spherical structure, while its flat interface provides a stable contact surface for fiber coupling and detector integration. This lens can convert point sources into collimated beams or focus incident light onto detector sensitive areas, making it widely applicable in fiber optic communications, spectral analysis, and near-field microscopy.
