There is a database of groups which use ellipsometry for scientific or industrial purposes. This database was initiated and collected by the Workgroup Ellipsometry at the Universität Leipzig.
The database lists ellipsometry users, their instruments with the main operation parameters, and current fields of interest. All information are based on contributions given by the users themselves. The users are responsible for their information.
