Abstract
An aplanatic microlens consisting of a sphere which is less than one millimeters in diameter. The sphere is made of a transparent material and has a plane surface ground into it so that the radial distance from the center of the sphere to the nearest point on the plane surface is equal to the radius of the sphere divided by the ratio of the index of refraction of the transparent material and the index of refraction of the medium which will surround the lens in use.
