A solid immersion lens (SIL) has higher magnification and higher numerical aperture than common lenses by filling the object space with a high-refractive-index solid material. SIL was originally developed for enhancing the spatial resolution of optical microscopy. There are two types of SIL: Hemispherical SIL: Theoretically capable of increasing the numerical aperture of an optical system by n, the index of refraction of the material of the lens.
