Abstract
A microscope apparatus includes an objective lens, an imaging lens, a pupil relay lens, and an image relay lens. The primary image of a specimen is formed between the imaging lens and the pupil relay lens, and the image of the pupil of the objective lens is projected between the pupil relay lens and the image relay lens so that a pupil modulator is disposed at the position of the projected pupil image. This arrangement makes it possible to produce pupil modulation, observe various specimens, and set the optimum position of an eyepoint.
