Patent ID: 7391564

Claim:
An infrared light condensing apparatus, comprising: a solid immersion lens for accepting an incident light or emitting an outgoing light, said solid immersion lens having a base plane on which a specimen is disposed in direct contact with the solid immersion lens; an antenna comprising an electrically conductive material, the antenna having a probe disposed away from said base plane of said solid immersion lens at a distance not more than ¼ of an effective wavelength of the light; a holder means for retaining said antenna; and a position control means for controlling a position of a tip of said probe by means of said holder means, wherein operating said position control means allows: the incident light to concentrate as a near-field at a desired position of the specimen on the base plane of said solid immersion lens or a near-field from a desired position of the specimen to be converted into a propagating wave corresponding thereto and then the propagating wave to be emitted as said outgoing light from said solid immersion lens.
