WebIn this case, the lens is called a positive or converging lens. For a thin lens in air, ... Note the sign convention: a telescope with two convex lenses (f 1 > 0, f 2 > 0) produces a negative magnification, indicating an inverted image. A convex plus a concave lens (f 1 > 0 > f 2) produces a positive magnification and the image is upright. WebSep 12, 2024 · The objective lens is a convex lens of short focal length (i.e., high power) with typical magnification from 5× to 100×. The eyepiece, also referred to as the ocular, is a convex lens of longer focal length. The purpose of a microscope is to create magnified images of small objects, and both lenses contribute to the final magnification.
