when a sample is placed in the focus of the convex lens of a microscope, a virtual, erect, and magnified image is formed at the least distance of the distinct vision. Parts of a simple microscope; mirror as illuminator, convex lens for magnification, stage and metallic stand with base. Us...
The condenser, a pivotal component of microscopes, exhibits a distinct physical structure that influences its functionality. Typically characterized by a cylindrical or prism-like shape, it is encased in a housing made of metal or plastic. This protective enclosure encompasses essential adjustment feature...
