    摘要： A cross-sectional area calculation section calculates a cross-sectional area of a subject as physical quantity with respect to a size of the subject, and an NEC calculation section calculates a noise equivalent count NEC as physical quantity for evaluating an image. The C-NEC calculation section calculates a noise equivalent count per unit area C-NEC as physical quantity for evaluating an image as per size of the subject in accordance with the cross-sectional area of the subject calculated in the cross-sectional area calculation section and the noise equivalent count NEC calculated in the NEC calculation section. Accordingly, the noise equivalent count per unit area C-NEC is calculated as noted above, whereby an index may be determined that is independent of the cross-sectional area of the subject in evaluating the image.

    摘要： The exposure time for obtaining a bright image in an image-acquisition optical system can be reduced, and shifting of an image visually observed in an observation-optical system is prevented, thus enabling stable observation. There is provided a microscope including an image-acquisition optical path for recording an image focused by an objective lens and an observation optical path for visually observing an image split-off from the image-acquisition optical path; and including an aperture stop, in the observation optical path, for stopping down the numerical aperture thereof to smaller than the numerical aperture of the image-acquisition optical path.

    摘要： An illumination system for microscopy includes a light source, a first spectral element dispersing light from the light source, a reflecting member selectively reflecting light dispersed by the first spectral element, a second spectral element combining light reflected by the reflecting member, a dichroic mirror, an objective lens, and an image sensor. The first spectral element is placed at the front focal point of a first lens, the reflecting member is placed at a position where the back focal point of the first lens coincides with the front focal point of a second lens, and the second spectral element is placed at the back focal point of the second lens.

    摘要： An optical apparatus minimizes autofluorescence and stray light as well as leakage of excitation light and efficiently utilizes illuminating light from a fluorescence illumination optical system to allow observation of a bright fluorescence image. An observation apparatus has an objective, an observation optical system unit including a variable magnification optical system, and an imaging optical system unit including an imaging lens and an eyepiece. A fluorescence illumination apparatus, which is provided separately, is removably attached to the observation apparatus. The fluorescence illumination apparatus has a light source, a collector lens unit, and a reflecting member placed between the objective and the observation optical system unit at a position displaced from the optical axis of the objective to make light from the light source incident on the objective. An excitation filter is provided between the light source and the reflecting member. An optical member for selectively transmitting fluorescent light emitted from a sample is placed between the objective and the observation optical system unit.
