Confocal Laser Scanning Microscope — Keyence VKx1100

Keyence VXx1100

The Analytical Instrumentation Facility (AIF) at NC State has recently installed the Keyence VKx1100, a Confocal Laser Scanning Microscope (CLSM). This microscope combines optical microscopy with laser profilometry, making it possible to obtain high resolution optical images and subsequently measure profile and surface roughness. It can be used for almost any type of material and is especially suited to measure surface features and roughness of samples which traditional stylus profilometry would not be feasible.
