Also 10x eyepiece module with a 3rd port for addition of a camera(not included) if required. modular in design makes this microscope a fine instrument that will last a life time Microplan objectives are included: 4x. Wires, apertures, micro defects, micro cavities, by rotating the image shearing you can measure in the x or y axis Many images may be measured at one time The image shearing process measures by comparing its exact image to its self. 50 micron diameter plus or minus 1 micron routinely fiber optics.

I find it useful for measuring electrodes for micro edm. the M 41 was designed and developed for the pattern generation micro measurements of the silicon wafer ladder etch. a 2 micron line can be measured plus or minus.2 micron easily. more traceable to NIST.01 MICRON AT HIGHER MAGNIFICATION ARE FEASABLE this a high quality microscope with an added feature of image shearing micro measurements. Oxidation during the spraying of thick steel deposits can happen in three main ways: (1) primary droplets in-flight prior to deposition (2) incorporation of secondary droplets generated by splashing (3) at the deposit top surface.M 41 Vickers Instrument Image Shearing Microscope features: compensation camera module micro measurements at 100x will give you plus or minus 1 micron. Differences in substrate shape, gun manipulation and oxygen entry point into the spray between chamber and spraying in a booth using a robot also alters the balance of oxidation and carbon loss processes. Under chamber spraying conditions, controlled additions of oxygen to the nitrogen atomising gas leads to an increase in deposition temperatures, better bonding with the substrate, a coarser microstructure, a decrease in deposit hardness and increased deposit brittleness through intersplat delamination and oxide cracking. The amount of oxidation and carbon loss can be reduced if spraying is carried out in a smaller, enclosed chamber. Even though nitrogen atomising gas is used to spray the steel, entrainment of oxygen from the surrounding atmosphere of the large extraction booth results in deposits that are high in oxide and substantially lower in carbon than the original steel feedstock wire. Twin wire electric arc spraying is being developed as a technique to form thick steel deposits for rapid production tooling by robotically manipulating several arc guns over a ceramic pattern.
