Abstract:
A microscope apparatus comprising:an objective lens adapted to relay an image of a specimen to infinity by collimating a beam of light from the specimen;an imaging lens adapted to form a primary image of the specimen from the beam of light emergent from said objective lens; andan image relay optical system adapted to relay said primary image to form a secondary image adjacent to an eyepiece and to project a pupil image of said objective lens,wherein said image relay optical system is configured such that a front side portion thereof is adapted to re-collimate the beam of light to cause a rear side portion thereof to receive a parallel beam of light, andwherein said image relay optical system includes a pupil relay lens adapted to project a pupil image of said objective lens and an image relay lens comprising a front lens unit and a rear lens unit, the front side portion of said image relay optical system containing said pupil relay lens and said front lens unit of said image relay lens, and the rear side portion of said image relay optical system containing said rear lens unit of said image relay lens.
