LIGHT SHEET ILLUMINATION MICROSCOPE

摘要

A light sheet illumination microscope includes an illumination optical system configured to illuminate a sample from a direction substantially perpendicular to an optical axis of a detection optical system. The illumination optical system includes a first optical element configured to convert light emitted from a light source into a light sheet that forms an illumination area having a sheet shape substantially perpendicular to the optical axis of the detection optical system when the sample is irradiated with the light sheet. The illumination optical system further includes a second optical element that configured to act on the light emitted from the light source such that the light sheet is converged or diverged in a width direction of the light sheet. The illumination optical system causes the light sheet to enter the sample at a predetermined constant angle from different positions in the width direction.
