Corning 7980 Cylindrical Rod Lens – Large Cylinder
Optical lenses are essential optical components designed to focus or diverge light. These can be single-element or multi-element systems, and they are widely used across various industries such as microscopy, laser processing, life sciences, imaging, industrial applications, and defense. As light passes through a lens, it is influenced by the lens’s shape and material. Plano-Convex (PCX) or Double-Convex (DCX) lenses focus light to a point, while Plano-Concave (PCV) or Double-Concave (DCV) lenses cause light to spread out. Achromatic lenses are ideal for color correction, and aspheric lenses help reduce spherical aberration. Infrared (IR) lenses made from materials like Germanium (Ge), Silicon (Si), or Zinc Selenide (ZnSe) are suitable for IR transmission, while Fused Silica is commonly used in ultraviolet (UV) applications.
Our products are used in a wide range of devices including cameras, lasers, medical equipment, laser printers, laser cutting machines, aerospace optical systems, optical communication transmitters, projectors, telescopes, microscopes, and magnifying glasses.
