Microscope Without Screws

3D Model

The macrometric and micrometric screws are two types of screws that are used in microscopes with screws to adjust the focus of the specimen. The macrometric screw is the larger screw that moves the stage up and down in large increments. It is used to quickly bring the specimen into approximate focus. The micrometric screw is the smaller screw that moves the stage up and down in small increments. It is used to fine-tune the focus of the specimen and achieve a sharp image. The macrometric and micrometric screws are usually located on the side of the microscope, near the base. For teaching. https://nunososorio.github.io/xredum/
