| 20150043049 | LIGHTING METHOD AND MICROSCOPIC OBSERVATION DEVICE - Standing wave-generating planar wave illumination units generate two light-wave planar waves using light from a light source assembly and irradiate a sample surface with a standing wave produced by interference of the planar waves on the sample surface.
