Abstract: An image can be prevented from becoming unclear over time during long-term observation. The invention provides a microscope apparatus including a specimen container for containing a specimen; an objective lens disposed opposite the specimen container for collecting light from the specimen in the specimen container; an immersion-liquid supplying unit for supplying immersion liquid to a space between the objective lens and the specimen container; and an immersion-liquid removing unit for removing the immersion liquid from the space between the objective lens and the specimen container. The immersion-liquid removing unit includes a nozzle for ejecting compressed air to the space between the objective lens and the specimen container.

Abstract: It is possible to check for observation success or failure and the observation history without waiting for observation to be completely finished, thus saving time and energy required for observation, and avoiding lost opportunities for observation of precious samples etc. Provided is a microscope apparatus including an image acquisition unit for acquiring a plurality of frame images while varying a plurality of parameters; an image saving unit for successively saving the frame images acquired by the image acquisition unit; a property-information saving unit for saving property information in which identifying information of the saved frame images is associated with the parameters; and a control unit for controlling these units, wherein the control unit saves updated property information in the property-information saving unit each time the frame image is saved in the image saving unit.

Abstract: It is possible to achieve a required field number and numerical aperture for microscope observation at a scanning speed equal to video-rate or higher and also to change the scanning speed with a simple configuration. The invention provides a laser microscope including a laser light source; a scanning unit configured to scan a specimen with laser light emitted from the laser light source; and an objective lens configured to focus the laser light scanned by the scanning unit on the specimen. The scanning unit is provided with an electro-optical deflecting element including an electro-optical crystal in which a refractive index gradient is induced by injecting electric current.

Abstract: A total internal reflection fluorescence microscope includes a light source which generates laser light having a plurality of wavelengths, a focal optical system which irradiates the laser light from the light source on a specimen at a predetermined incident angle via an objective lens and which generates evanescent illumination, a fluorescence observation unit which observes fluorescence generated from the specimen due to the evanescent illumination, an incident angle adjuster which adjusts the incident angle of the laser light irradiated on the specimen, and a controller which controls the incident angle adjuster such that the amount of the permeation depth of the evanescent light is the same when the wavelength of the laser light from the laser light source is switched.

Abstract: A laser scanning microscope includes an acousto-optic element or an electro-optic element in an illumination optical system which introduces a laser beam from a laser beam source of the laser scanning microscope into a microscope.
