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.
