LENS Meaning and Definition

  1. A lens is an optical device which is typically made of transparent material, such as glass or plastic, with curved surfaces that refract and focus light to form an image. It is a fundamental component used in various optical systems to manipulate and control the path of light, enabling the formation of clear and magnified images.

    Lenses are classified based on their shape and purpose. Convex lenses are thicker at the center and thinner at the edges, causing light rays passing through to converge at a specific point, forming real or virtual images. They are commonly used to correct farsightedness and to magnify objects, as in cameras and binoculars. Concave lenses, on the other hand, are thinner at the center and thicker at the edges, resulting in light rays diverging. They are used to correct nearsightedness and can be found in eyeglasses.

    In addition to shaping and focusing light, lenses can also alter the properties of light such as its direction, speed, and intensity. They are extensively employed in applications such as microscopes, telescopes, projectors, and various optical instruments used in scientific research, photography, medicine, and telecommunications.

    Overall, lenses are essential tools in the field of optics, harnessing the physics of light to provide clearer vision, aid in scientific discoveries, and improve the quality of visual devices.

  2. A piece of glass, quartz, or other transparent substance with one or both surfaces curved, either concave or convex; used for acting upon the rays of light in the way of convergence or dispersal.

Etymology of LENS

The word "lens" stems from the Latin word "lentilis", which means "lentil" due to the resemblance of a lentil bean's shape to a biconvex lens. In Latin, lentilis was used to describe the shape of various lens-like objects, and over time, the term "lens" came to refer specifically to the optical instrument.

Idioms with the word LENS

  • Fresnel lens A Fresnel lens is an optical lens that is composed of several concentric rings or grooves on its surface, which help to reduce the overall weight and thickness of the lens while maintaining its optical properties. This type of lens is commonly used in lighthouses, projectors, and other optical devices to focus or concentrate light.
  • Fres·nel lens A Fresnel lens is a type of lens that consists of a series of concentric rings or grooves on its surface, allowing it to be much thinner and lighter than a traditional lens. These lenses are commonly used in lighthouses, projectors, and other optical devices to focus or diffuse light.
