Focal length and refractive index relation
WebApr 2, 2024 · Focal length f: 1 f = ( μ − 1) ( 1 R 1 − 1 R 2), where μ is the refractive index, R 1 is the radius of curvature of the surface close to the object, and, R 2 is the radius of curvature of the surface farther away from the object. We have two cases: one with the convex lens in air and one with the convex lens immersed in water. WebApr 6, 2024 · This allows the transmission phase at the nanoscale to be controlled by the hole diameter. We fabricated an EUV metalens with a 10-millimeter focal length that supports numerical apertures of up to 0.05 and used it to focus ultrashort EUV light bursts generated by high-harmonic generation down to a 0.7-micrometer waist.
