The SEM LEO was a very reliable and rugged instrument that provided high quality SEM  images of most samples and it served the users of the cleanroom for many years. Excellent images on a large variety of materials such as semiconductors, semiconductor oxides or nitrides, metals, thin films and some polymers were acquired by the thousands on the SEM.

In her later years the SEM LEO was equipped with a Raith e-beam lithography system and was exclusively dedicated to the users of the Raith E-beam lithography. Decommissioned in early summer 2020, she is at DTU Mechanics.
