    Infinity Corrected Objectives

    Infinity Corrected Objectives are used in a variety of imaging or laser focusing applications. Infinity Corrected Objectives are microscope objectives that focus at infinity. Infinity Corrected Objectives offer long working distances, along with the ability to place optical components such as optical lenses or optical filters into the optical path. When used in imaging applications, Infinity Corrected Objectives require a secondary lens to be placed in the optical path to focus the collected light from the specimen onto the sensor. In laser applications, a secondary lens is not needed.

    Edmund Optics offers a wide variety of Infinity Corrected Objectives, including Mitutoyo Objectives, Olympus Objectives, Nikon Objectives, or Zeiss Objectives. Mitutoyo Objectives are available for use with Mitutoyo microscopes or accessories in applications from the ultraviolet to the infrared. Mitutoyo Objectives are ideal for use in industrial applications. Olympus Objectives are available for use with Olympus microscopes or accessories. Olympus Objectives are ideal for use in life science applications.
