摘要： Provided is an objective optical system employing a gradient index (GRIN) lens. A refractive index of the GRIN lens is changed in an axial direction and a direction perpendicular to the axial direction. The GRIN lens has a refractive index n satisfying the following equation: n ⁡ ( r , z ) = ∑ i = 0 ⁢ ⁢ n r2i ⁢ r 2 ⁢ i + ∑ j = 0 ⁢ ⁢ n zj ⁢ z j where z is a distance from the center of the lens in the axial direction and r is a distance from the center of the lens in the direction perpendicular to the axial direction. Thus, an objective optical system with a high numerical aperture can correct aberration.

摘要： A method of manufacturing a micro-lens in which at least one first lens is first molded using a compression technique. A lens holder is produced including a hole in which the first lens is seated. A second lens is formed on a bottom surface of the lens holder. The first and second lenses are combined by aligning the first and second lenses along an optical axis in the hole of the lens holder. Thus, a hybrid micro-lens composed of a diffractive lens and a refractive lens, along with an array of the hybrid micro-lenses are easily manufactured.
