Infinity Corrected Objectives

Infinity corrected objectives are optical systems, commonly used in microscopes, that have any image distance that is set to infinity. They are commonly used in industrial metallurgical microscopes and research laboratory microscopes. The main advantage of an infinity corrected objective is that the magnification doesn’t change even when the distance between the tube lens and the objective lens is changed. Types of infinity corrected objectives include tube lenses, C-mount microscopes, and focusing objectives. Major manufacturers of infinity corrected objectives include Leica, Nikon, Olympus and Zeiss. Infinity corrected objectives are used in a wide range of imaging and laser focusing applications including science and research, engineering, botany, entomology and astronomy.
