Achromatic lenses cemented together eliminate extraneous colors, providing an accurate depiction of an object. Two plano-convex lenses correct the image for distortion-free viewing side-to-side. Achromatic and aplanatic lenses work together to provide a magnified image that is free of distortion and color aberration. The black metal lens frame protects the optics from damage. The optics can be pivoted into the chrome-plated brass handle to protect the magnifier from damage while not in use.
