Witryna20 lut 2011 · First, I should point out that a typical microscope does not consist of two convex lenses. Instead, a microscope consists of an objective and an eyepiece. Microscope … WitrynaLenses may be divided broadly into two main types: convex and concave. Lenses that are thicker at their centers than at their edges are convex, while those that are thicker around their edges are concave. A light beam passing through a convex lens is focused by the lens on a point on the other side of the lens. This point is called the focal point.
