The objective lens of a microscope is the one at the bottom near the sample. At its simplest, it is a very high-powered magnifying glass, with very short focal length. This is brought very close to the specimen being examined so that the light from the specimen comes to a focus inside the microscope tube.The objective lens is made up of many lenses that work together to magnify an item and produce a bigger picture. Objective lenses could be utilized for a variety of purposes, including extreme magnification and spatial filtering.A convex lens is thicker at the center than the edge and will focus a beam of light to a point a certain distance in front of the lens (the focal length). A concave lens is the opposite, being thicker at the edge than the center and spreading out a beam of light. Microscopes use convex lenses in order to focus light.
