An achromatic lens can be defined as a lens which is made by acombination of two different types of lenses carrying different focal powers in a manner such that the images formed by the light of both the combined lenses are free from chromatic aberration or achromatism.

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. Elyonoptic offers a variety of Ball Lenses in a range of substrates for performance in the ultraviolet to the NIR.

Double Convex Lenses are used in image relay applications, or for imaging objects at close conjugates. Double Convex Lenses have positive focal lengths, along with two convex surfaces with equal radii. Aberrations will increase as the conjugate ratios increase. DCX Lenses are used in a range of industries or applications.
-

Double Concave Lenses are used in beam expansion, image reduction, or light projection applications. These lenses are also ideal for expanding the focal length of an optical system. Double Concave Lenses, which have two concave surfaces, are Optical Lenses with negative focal lengths.

The Plano-Convex (PCX) lens causes light to focus to a point,it has a positive focal length,which is ideal for light collimation or for focusing applications utilizing monochromatic illumination, in a range of industries. Uni-Optics offers PCX lenses with a variety of coating options.
-

Meniscus lenses have two curved surfaces,convex on one side and concave on the other side. It is thicker at the center than at the edges. When a meniscus lens is combined with another lens, the focal length is shortened and the numerical aperture of the system is increased.

ZnSe Plano Convex Lenses are precision infrared optical components manufactured from Zinc Selenide (ZnSe). Featuring one flat surface and one convex surface, these positive lenses are designed for focusing, collimating, and collecting infrared radiation in laser and imaging systems. With its broad infrared transmission range, ZnSe is well suited for CO₂ laser optics, thermal imaging…
