INCIDENT ILLUMINATION APPARATUS FOR A MICROSCOPE WITH PLANAR LIGHT SOURCE

摘要

The invention relates to an incident illumination apparatus for a microscope for observing a sample (1) in the microscope (10), with a planar light source (100) for incident illumination of the sample (1), wherein the planar light source (100) comprises a plate-shaped optical waveguide with a lower interface (111), an upper interface and at least one side face as well as at least one illumination means, which is arranged in such a way that it radiates light into the optical waveguide via at least one side face serving as light-entry face such that said light propagates in the optical waveguide due to total internal reflection, wherein the total internal reflection is interfered with in a defined manner by an element adjoining a contact face on the lower interface of the optical waveguide in such a way that there is decoupling of light on the upper interface of the optical waveguide.
