Claim:
An adaptor for a liquid immersion type microscope, the microscope including a support member for supporting a specimen thereon, a liquid immersion type objective lens, a discharging member for discharging a liquid between a front edge of the objective lens and the specimen, and a sucking member for sucking the liquid from the specimen, the adaptor being attached to the liquid immersion objective lens and arranged between the lens and the specimen when observing the specimen with the microscope, said adaptor comprising: a body member having a connecting portion configured to be attached to the liquid immersion objective lens at a periphery of the front edge such that a front lens element of the objective lens is exposed at a central portion of the body member; the body member having inclined surfaces on a side of the body member opposite the front edge of the objective lens, a first portion of each inclined surface being adjacent to the front lens element of the objective lens, the inclined surfaces being angled such that each inclined surface gets closer to an image side of said liquid immersion objective lens as it gets farther away from the front lens element, one of the inclined surfaces extending from the first portion thereof adjacent the front lens element to a second portion thereof at a side face of the objective lens; the body member having protruded portions adjacent to said inclined surfaces and protruding toward an object side of said liquid immersion objective lens such that an aperture portion is formed at the second portion of said one of the inclined surfaces, the aperture portion being bounded by said protruded portions and the specimen at the second portion at the side face of said liquid immersion objective lens.
