Both stands are equipped with a motorized Z-axis, enabling extended-depth-of-field and 3D imaging. Regardless of the zoom lens installed, they are therefore capable of capturing image sequences for subsequent processing into extended-depth-of-field or 3D images.
Both allow for reflection or transmission modes, with different light directions and diffusers, and can be equipped with light-diffusing polarizers. This makes them versatile tools suitable for a wide range of materials and applications.
The first microscope stand, featuring a motorized Z-axis and manual X and Y axes, is equipped with a zoom range from 500x to 5,000x.
The second stand can accommodate two zoom lenses: one with a range of x20 to x200 and the other from x100 to x1000. It has motorized X, Y, and Z axes, allowing it to perform mapping by covering large areas through the stitching of multiple images. This mapping mode can be combined with extended focus (increased depth of field) or 3D acquisition.
This image was captured using the Keyence digital microscope (Z20 objective) through a 2D image stitching process. It shows a cross-section of a wall produced by wire arc metal additive manufacturing (martensitic 415 stainless steel) and electrolytically etched with HF. The 10 layers that were successively deposited onto the substrate—each with a different microstructure—can be seen, as well as the indentations from the hardness tests performed earlier.
