What is a step gauge? What is the working principle of a step gauge?

A profilometer is a precision instrument used for high-precision measurement of the microscopic topography of material surfaces (such as step height, roughness, flatness, and warp). It is widely used in semiconductor manufacturing, materials science research, MEMS (Microelectromechanical Systems) processing, and optical component testing. Its core function is to obtain quantitative data on surface height changes through minute contact between the probe and the sample surface, providing key data for material performance analysis and process optimization.

For biological sample imaging, which is better: a field emission gun (FEG) or a tungsten filament gun in a scanning electron microscope?

In life science research, the scanning electron microscope (SEM) is a core tool for revealing the microstructure of biological samples. From cellular ultrastructure to virus particles, from tissue sections to biomaterial interfaces, biologists' need to "see clearer and finer" is increasingly urgent. The core component of the scanning electron microscope—the electron gun (field emission electron gun FEG vs. tungsten filament gun)—is the key to determining imaging capabilities.
