In the world of big-time, small-scale characterization, the Lehigh Microscopy School has been leading the way for 50 years, and shows no signs of slowing down. The first Lehigh Microscopy School was held in the summer of 1970 with three lecturers, a dozen students and a single scanning electron microscope (SEM). Since then it has grown to become the largest school of its kind in the world. The school offers basic and advanced courses that combine theory with lab practice. Manufacturers provide additional equipment to complement the suite of scanning and transmission electron microscopes available in Lehigh’s Nanocharacterization Laboratory, one of the largest of its kind in the world. Course offerings at the Lehigh Microscopy School include: Introduction to SEM (scanning electron microscopy) and EDS (energy dispersive X-ray spectroscopy) for the New SEM Operator, Transmission Electron Microscopy, and Focused Ion Beam Instrumentation and Applications. All courses include a lab component where small groups of students can experience practical applications of the lecture topics. The 2020 Lehigh Microscopy School is set for May 31-June 5, 2020.
