Tungsten needles are made from the material with high melting, high density, good corrosion resistance and electrical conductivity. They can be used for several applications in microscopy. Specifically, the following are common applications: Atomic Force Microscope (AFM): An atomic force microscope is a high-resolution surface topography measurement instrument. In AFM, needles made of tungsten are used as probes or probes. They interact with the sample surface to acquire high-resolution topographical images and measure surface forces and properties.
