Abstract
The invention provides a microscope having high utilization efficiency of light from a light source and capable of using a bright, uniform line illumination. The microscope includes a plurality of light sources; a collimator lens that substantially collimates light from the light sources; a cylindrical lens having a flat surface orthogonal to the optical axis of light emitted from the collimator lens, and a cylindrical surface whose longitudinal axis is disposed parallel to the arrayed direction of the light sources; and an objective lens that illuminates a specimen with light from the cylindrical lens.
Claims1
