摘要： A microscope optical system having an objective lens, an observing direction converting prism bending a beam of light from the objective lens in a predetermined direction, and an eyepiece for observing an image formed by the beam of light bent in the predetermined direction comprises a first prism having the same bottom angle as the observing direction converting prism, replaceable with respect to the observing direction converting prism, a loop optical path comprised of an odd number of reflecting members for conducting the light beam transmitted by the first prism in the predetermined direction, and a photographic lens provided in the loop optical path. Thus, the microscope optical system has important advantages in practical use that where image recordings are made in photography and video, the field range and the position of a photographic image can be observed as they are through the eyepiece, magnification is variable without rendering the lens barrel large, and the structure is simple with low cost.

摘要： A phase contrast microscope including an illuminating optical system, a ring slit arranged at a pupil of the illuminating optical system, an imaging optical system, and a phase plate arranged at a pupil of the imaging optical system which is conjugate with the pupil of the illuminating optical system with respect to a specimen plane on which a specimen under inspection is placed. The phase plate is formed by a liquid crystal and a pair of transparent ring-shaped electrodes arranged on both sides of the liquid crystal. A voltage applied across the liquid crystal via the electrodes is changed such that a phase difference introduced by the phase plate is set to .+-..pi./2 to obtain a dark contrast image and a bright contrast image. A difference between these dark and bright contrast images is derived to obtain a phase contrast image having high contrast and resolution.
