    摘要： There is provided: an optical system including a focus lens group having positive refractive power and configured to move along an optical axis when focusing from an infinite-distance object to a short-distance object, and satisfying predetermined conditional expressions; and an imaging device including the optical system. The focus lens group includes a lens subgroup A, an aperture stop, and a lens subgroup B in order from the object side. The lens subgroup A includes a negative lens, a positive lens, and a positive lens in order from the image side. The lens subgroup B includes a negative lens and a positive lens in order from the object side.

    摘要： In a plasmonic structure, a first conductor layer, a dielectric layer, and a second conductor layer are stacked in this order. The second conductor layer includes a plurality of conductor patterns that is two-dimensionally and periodically arranged, each of the plurality of conductor patterns having a circular shape or a regular polygonal shape. A diameter D of a circle circumscribed on each of the plurality of conductor patterns satisfies 200 nm≤D≤800 nm. A thickness g of the dielectric layer and the diameter D satisfy 0.3≤g/D≤0.6.
