    Ball and Condenser Lenses

    Ball Lenses are commonly used to improve signal quality in fiber coupling applications, or for use in endoscopy or bar code scanning applications. Ball Lenses feature short back focal lengths to minimize the distance needed from the Ball Lens to the optical fiber. Edmund Optics offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR. Half-Ball Lenses are also available to ease mounting or system integration.

    Condenser Lenses are used in high efficiency illumination or projection systems. Condenser Lenses are optical lenses designed to gather light while correcting for spherical aberrations or coma. Edmund Optics offers a variety of Condenser Lenses. Aspheric Condenser Lenses can effectively replace multiple element systems by reducing the number of back reflections, thereby increasing the overall transmission. By replacing a multiple element design, the complexity and size can be decreased. Condenser Lenses are often used in pairs with their convex surfaces nearly in contact.
