Text__xOzAgKOcEd-WfYQ0GneCwQ_text=The ultramicroscope makes it possible to see structures that remain hidden to a  normal microscope. An object is diagonally flooded with light, so that the direct path  of the light past the lens and the picture is generated only by light that is scattered at  the object. The process is developed in 1903 by the chemist Richard Zsigmondy in  cooperation with Zeiss. Jean Perrin uses an ultramicroscope to study the Brownian  Motion of minute spheres and confirms the results predicted by Einstein in 1905.
