Abstract:
A lens system includes a first lens which is formed of a medium exhibiting negative refraction and a second lens which is formed of a medium having a positive refractive index. Abbe's number for a material which forms the first lens differs from Abbe's number for a material which forms the second lens. Moreover, a lens system includes a first lens which is formed of a medium exhibiting negative refraction and a second lens which is formed of a medium exhibiting negative refraction. Abbe's number for a material which forms the first lens differs from Abbe's number for a material which forms the second lens.
