Calibrated Digital Microscopes
We have a number of different devices for obtaining digital micro images. This particular microscope has up to 200x magnification. The images are then measured on the computer.
Magnification: 2-100x Software: Motic Images Plus Camera Resolution: 3.1-10.2MP
This is a 2D stylus based profilometer. A sharp stylus (typically 2microns tip radius) is drawn across the surface. The normal deflection of the stylus is amplified, digitised, and processed on a PC. From this, it is possible to infer a great deal of information about the surface of a material. The device is commonly used to measure wear scars and wear volume
These devices are used to measure the hardness of materials. It is possible to give Vickers, Knoop, Brinell, and some Rockwell scale hardness's. Hardness is measured via the controlled indentation of a material by a pointed or curved indenter (usually a pyramid or sphere). The hardness is then calculated as the indentation load divided by the area of the impression. The centre has micro and nano scale hardness testers; the latter also allowing the determination of elastic modulus.
