Abstract
The invention provides a microscope in which the utilization efficiency of light from light sources is high and which can use a bright, uniform line illumination. The microscope includes a plurality of light sources; a fly-eye lens having a plurality of lens elements arrayed in a rectangular shape corresponding to the light sources, the light sources being disposed at the focal points thereof; a cylindrical lens having a flat surface orthogonal to the optical axis of light emitted from the fly-eye lens, and a cylindrical surface whose longitudinal axis is disposed parallel to the arrayed direction of the fly-eye lens; and an objective lens that illuminates a specimen with light from the cylindrical lens.
