Description
Photon collection plays an important role in super-resolution microscopy, where localization precision strongly depends on the number of detected photons. Here, we present a new lens system combining a semi spherical solid immersion lens with an aspherical relay lens, designed to achieve an effective numerical aperture above 2.0 and near-unity collection efficiency. In addition to improving photon collection and spatial resolution in microscopy, the system is particularly suited for efficient collection from single-photon emitters. The presented design combines diffraction-limited performance with a high degree of adaptability while accounting for manufacturing constraints and the cryogenic environment required for the experiments.
