The reflecting/refracting optical element has a first face formed on the front-direction-object side, a second face formed on the image side, and a third face formed as a transmitting surface between the first face and the second face. The first face has a first transmitting surface formed with the optical axis being at a center thereof and a first reflecting surface annularly formed around the first transmitting surface and directed toward an image side. The second face has a second transmitting surface formed with the optical axis being at a center thereof and a second reflecting surface annularly formed around the second transmitting surface and directed toward the front-direction-object side. A movement of the moving lens component changes the refracting power ratio of the front group to the rear group, to enlarge or shrink, in the entire observation region, a region in which an image of the front-direction object is formed.

摘要： Microscope objective lenses are disclosed that comprise an axially movable second lens group for correcting aberrations that arise with changes in the thickness of a cover glass or other transparent body situated between the specimen and the objective lens. An objective lens according to one aspect of the invention comprises, in order from the specimen side, first, second, third, and fourth lens groups. The first lens group is positive and comprises a negative lens cemented to a positive lens, the positive lens having a convex surface facing the specimen side. The second lens group is positive and comprises a cemented lens having a cemented surface having negative refractive power. The third lens group is positive and causes a ray bundle from the specimen, propagating divergently from the specimen, to converge toward the optical axis. The fourth lens group is negative and comprises a positive lens cemented to a negative lens, the negative lens having a concave surface facing the image side. Moving the second lens group on the optical axis allows correction of aberrations imparted by a transparent body between the specimen and the objective lens. The objective lens satisfies one or more conditional expressions.
