Abstract:
1. A microscope comprising: an illuminating device which emits light from a light source to an object, and which generates a luminous flux including information of the object; an illuminating light modulating device which modulates at least one of wavelength, phase, intensity, polarization, and coherency of the light emitted to the object by the illuminating device; an objective lens and an imaging lens which focus the luminous flux including the information of the object to form an image of the object; a pupil modulating device which is disposed near a pupil plane of the objective lens, and which modulates at least one of phase, intensity and direction of polarization of the luminous flux including the information of the object; an image pickup device which is disposed on a plane on which the image of the object is formed by the objective lens and the imaging lens, and which picks up the image of the object; an image display device which displays the image of the object picked up by the image pickup device; an image analysis device which analyzes the image of the object picked up by the image pickup device; a parameter decision device which adjusts modulation amounts of the illuminating light modulating device and the pupil modulating device using the image information of the object analyzed by the image analysis device, wherein at least one pupil transmission optical system is disposed between the objective lens and the imaging lens, wherein a plane conjugate with the pupil plane of the objective lens is set between the objective lens and the imaging lens by the pupil transmission optical system, wherein said pupil modulating device is disposed near the conjugate plane, wherein said pupil transmission optical system comprises a telecentric optical system including a first lens group and a second lens group, and wherein a rear side focus plane of the first lens group and a front side focus plane of the second lens group substantially coincide with each other, and the front side focus plane of the first lens group substantially coincides with the pupil plane of the objective lens.
