Apparatus for fixing solid immersion lens

摘要

Provided is an apparatus for fixing a solid immersion lens (SIL) in an optical system. The apparatus includes a first adapter; a second adapter screw-coupled to the inner surface of the first adapter and screw-coupled to the outer surface of a third adapter to pressurize a first O-ring; the third adapter screw-coupled to the inner surfaces of the second adapter and a fourth adapter; the fourth adapter screw-coupled to the outer surface of the third adapter to pressurize a second O-ring; the first and second O-rings elastically fixing an outer surface of a barrel of an infrared ray (IR) objective lens; and an SIL holder mounting the SIL onto the first adapter.

主权项

1. An apparatus for fixing a solid immersion lens (SIL) in an SIL optical system, comprising:
a first adapter at which the SIL is mounted the first adaptor being configured to adjust a distance from an infrared ray (IR) objective lens and a focal length from a specimen by adjusting a location of the SIL, to be in close horizontal contact with the specimen; a second adapter screw-coupled to an inner surface of the first adapter and screw-coupled to an outer surface of a third adapter to pressurize or depressurize a first O-ring, the first O-ring being disposed between the second adaptor and one end portion of the third adaptor; the third adapter screw-coupled to inner surfaces of the second adapter and a fourth adapter; the fourth adapter screw-coupled to the outer surface of the third adapter to pressurize or depressurize a second O-ring, the second O-ring being disposed between the other end portion of the third adaptor and the fourth adaptor; the first and second O-rings configured to elastically fix an outer surface of a barrel of the IR objective lens by an expansion due to pressurizing forces of the second adapter and the fourth adapter; and an SIL holder configured to mount the SIL onto the first adapter.
