    摘要： The present relates to chromatic focusing via filter thickness tuning. Chromatic focusing can be achieved via an imaging system that includes a sample holding plane, a light source that illuminates the sample on the plane, and an imager that captures an image of the sample on the plane. The imager includes a sensor, a lens, and a filter wheel defining a plurality of filter apertures including a first aperture containing a first filter passing light of a first color and having a first focal point shift, and a second aperture containing a second filter passing light of a second color and having a second focal point shift. The focal point shifts cause both light of the first color passing through the first filter and through the lens and light of the second color passing through the second filter and through the lens to focus on the sensor.

    摘要： An observation device including: a stage having a transparent pedestal surface; an illumination system under the pedestal surface, the illumination system emitting illumination light toward the pedestal surface; and an object system under the pedestal surface for capturing transmission light generated from the illumination light, reflected off a reflection surface and transmitted through a sample. Wherein a first light path in the illumination system is different from a second light path in the object system, in a first pupil surface of the illumination system, the illumination system generates the illumination light by restricting light in a first transparent region, in a second pupil surface of the object system, the object system restricts the transmission light in a second transparent region, and the second transparent region has first and second subregions with different transmittance, the second subregion located between the first subregion and an edge of the second transparent region.

    摘要： An optical observation device having an imaging optical system for forming an image of light from an object on a sample stage, a movement information retaining unit for retaining the movement information on the sequence of the movement to each relative position and a plurality of relative positions of the sample stage to the imaging optical system, a moving unit for moving the sample stage and allowing the stage to rest at each relative position, an imaging data acquisition unit for continuously acquiring the imaging data of observation images obtained by the imaging optical system at a time interval shorter than the time to move the stage to each relative position and the time of rest at each resting position, and a discrimination information providing unit for providing to the imaging data discrimination information for distinguishing whether the imaging data is imaged at a timing when the stage is moving.

    摘要： A microscope and a microscopy method for imaging an object, wherein use is made of a microscope comprising an objective which defines an optical axis and a focal plane perpendicular thereto, and an adjustable correction optical unit which, at the objective, corrects a spherical aberration occurring when imaging the object with a certain depth position of the focal plane. The method comprises the following steps: determining an actual type of object; reading a database in which refractive indices of different types of objects are stored in order to determine the refractive index of the object; using a relationship between the refractive index and the spherical aberration caused by the object in order to ascertain an adjustment value of the correction optical unit such that there is a reduction in the spherical aberration in the focal plane; adjusting the correction optical unit to the adjustment value; and imaging the object.
