ABSTRACT:
A microscope objective lens system comprising a plurality of lenses, at least one of the lenses being a graded refractive index lens (GRIN lens) whose refractive index varies as the radial distance from the optical axis varies, which is simpler in construction and in which aberrations are corrected sufficiently to a wide range of NA.
