ABSTRACT:
Disclosed is an optical probe for obtaining a micro spot light, comprising a rod-like glass body having a rectangular cross section as a core for propagating a light wave. The distal end portion of the glass body is gradually diminished toward the distal end so as to form a micro distal end face having a small diameter. The side surface of the distal end portion of the glass body in a direction perpendicular to the polarized direction of the light wave is coated with a light absorber formed of a metal film.
