Changes in DC magnetic field levels near an electron microscope or e-beam lithography tool degrade image quality and inhibit production. A change in DC fields often results in image distortion, a blurred image, or image drift

A site survey for an electron microscope, analytical equipment, or a sensitive manufacturing tool is a critical requirement whenever purchasing a piece of equipment or moving into a new laboratory or cleanroom.

Discussion: Reducing Vibration from Mechanical Equipment in an Electron Microscopy Lab: Laboratories often have vibrating equipment that causes disturbances on electron microscope images.
