摘要： In the present invention, a transmission-illumination apparatus for use in a microscope has a transmission-illumination optical system comprising a condenser lens for radiating light emitted from a light source onto a sample, and an observation optical system including an objective lens for observing the sample. At least two shield members for controlling a shape of an aperture created in a pupil of the objective lens are disposed at or near positions conjugate with a pupil position of the objective lens. Thereby, a contrast can be successively varied without disposing a purpose-specific optical element, etc. in the observation optical system, and illumination with an optimal contrast can be provided for various samples.

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.

摘要： The invention relates to a microscope zoom objective lens system having improved optical performance, and comprising a compact optical system with a zoom ratio of at least 3. The microscope zoom objective lens system comprises a first lens group G1 having positive refractive power, a second lens group G2 having negative refractive power and a third lens group G3 having positive refractive power. For zooming from a low to a high magnification side, the second and third lens groups G2 and G3 move along the optical axis while the separation between the first lens group G1 and the second lens group G2 becomes wide and the separation between the second lens group G2 and the third lens group G3 becomes narrow. The first lens group G1 comprises at least one doublet having positive refractive power and consisting of a positive lens and a negative lens. The positive lens has an Abbe number defined by null>80.
