    • The present invention, which relates to a near-field lens optical system, provides a near-field lens fixing device that is formed to include a first adapter where a near-field lens is disposed and the coupling height of the near-field lens is adjusted so that a gap between infrared object lenses and a focal distance from a specimen are adjusted, the first adapter being in close and horizontal contact with the specimen; a second adapter that is screw-coupled with an inner surface of the first adapter and is screw-coupled with an outer surface of a third adapter so that a first O-ring is pressed or released; the third adapter that is screw-coupled with inner surfaces of the second adapter and a fourth adapter with O-rings being positioned in both end portions of the third adapter; the fourth adapter that is screw-coupled with the outer surface of the third adapter so that a second O-ring is pressed or released and the first O-ring and the second O-ring that expand due to pressing forces of the second adapter and the fourth adapter and elastically fix an outer surface of a body tube of the infrared object lens; and a near-field lens holder that is used to mount the near-field lens on the first adapter. Difficulties associated with optical axis alignment and focusing of the first adapter, on which the near-field lens is mounted, through a screw movement are addressed, and object lens performance decline attributable to a screw coupling force acting on the object lens can be prevented since the body tube of the object lens is coupled with the near-field lens fixing device by using an elastic expansive force of the O-ring. A horizontal and close contact state is maintained between the near-field lens and the specimen by a long hole of the first adapter that has a spring function. The performance of the near-field lens can be realized with greater ease and excellent, and an accident in which the specimen or the near-field lens is damaged can be prevented.
