    Finite Conjugate Objectives

    Finite Conjugate Objectives are used in a variety of simple microscopy setups or for OEM integration. Finite Conjugate Objectives are microscope objectives that do not require a secondary lens to focus onto a specimen. Finite Conjugate Objectives are typically optimized for use in the visible spectrum. Focusing objectives typically contain about three lens elements, decreasing size and weight. These microscope objectives are less expensive alternatives to Infinite Conjugate Objectives for a wide range of commercial applications.

    Edmund Optics offers a variety of Finite Conjugate Objectives in achromatic, planar, or semi-planar designs. Achromatic focusing objectives have a flat field in about the center 65% of the image. Semi-planar focusing objectives have a flat field in about 80% of the image. Many of these focusing objectives can be used interchangeably with standard microscope objectives. These microscope objectives are a single objective solution for focusing applications, removing the need to purchase additional focusing components.
