It is an object to provide a zoom microscope of a simple structure which can expand a variable-power range. In order to achieve the object thereof, the zoom microscope includes a replaceable infinity correction objective lens, an aperture stop, an afocal zoom system, and an imaging optical system which are arranged in this order from a specimen side. Further, the aperture stop is disposed on or near a rear focal plane of the objective lens.

A microscope system includes a transmission illumination optical system having a light source and a condenser lens; a first dry objective having a magnification of from 20 or higher to 40 or lower and capable of viewing by at least one of a differential interference viewing method and a modulation contrast viewing method; and a second dry objective having a magnification of from 60 or higher to 100 or lower and capable of viewing by a differential interference viewing method; the first objective and the second objective being exchangeable.

A modulation contrast microscope that affords good view of sperm in ICSI, in particular, good view during sperm manipulation in ICSI, by improving contrast of the end portion of the tail includes the modulation contrast microscope comprises an aperture member having a partial aperture disposed at or near the front focal plane of a condenser lens, and a modulator disposed at a plane substantially conjugate with the aperture member, at or near the rear focal plane of a first objective lens or a conjugate plane thereof. The transmittance T(%) of a region of the modulator, corresponding to the partial aperture, satisfies the condition 1 £ T £ 8. Good viewing for ICSI sperm manipulation can be obtained as a result.

An image input system includes an image input device for reading image information from a source document and a feeder for automatically inserting the source documents into the image input device. The feeder includes a loading magazine storing source documents and an adjacent discharge magazine storing source documents discharged from the image input device. The source documents travel along a transport surface within the feeder. A dividing board controls the position of the source documents within the feeder. Detectors are provided to monitor the loading operation. A method of reading image information using the image input system is also disclosed.

A microscope for introducing light from a light source via an objective lens to a sample so that a user observes the sample via the objective lens includes: a minute opening arranged in an optical path between the light source and the objective lens and on a focal plane of the image side of the objective lens or at a position conjugate with its conjugate plane; position adjusting means for adjusting the position of the minute opening so that the light from the light source via the minute opening is incident to the sample at the Brewster's angle; an polarizing element arranged in the optical path between the light source and the objective lens for extracting rectilinear polarized light from the light from the light source and applying the rectilinear polarized light to the sample.

摘要:
A minute particle optical manipulation method and a minute particle optical manipulation apparatus are capable of simply strengthening a trapping force in an optical-axis direction and expanding a range where the trapping for acts in the optical-axis direction without requiring an optical element such as a special prism etc., and obtaining the trapping force enough to trap the particle even when the minute particle exists deep within a medium while keeping the trapping force when the minute particle is in a shallow position within the medium.
