Advanced Surface Analysis

Main content

While changing surfaces is, perhaps, the major activity at LSST, the ability to understand how those surfaces have been changed is equally important, and for this reason, we have developed a number of new surface-analytical approaches. These include the extended surface forces apparatus, an infrared method for in situ characterization of sliding, lubricated contacts, and approaches to nanochemical imaging, by means of atomic force microscopy.
