If a piece of glass or other transparent material takes on the appropriate shape, it is possible that parallel incident rays would either converge to a point or appear to be diverging from a point. Therefore, a transmissive optical device that focuses or disperses a beam of light by means of refraction is referred to as a lens. A convex Lens also known as a converging lens is a lens that converge rays of light that are travelling parallel to its principal axis. The edges of a convex lens are curved outward rather than inward.

Difference between convexo-concave and concavo-convex lenses?

Lenses bend light in useful ways. Most devices that control light have one or more lenses in them some use only mirrors, which can do most of the same things that lenses can do. See a demonstration opens a new window of what happens to the light path when you combine several convex or concave lenses. Perfectly straight, until something bends it. Simple or Complex? Simple lenses can't form very sharp images, so lens designers or optical engineers figure out how to combine the simple types to make complex lenses that work better.

These two devices use these types of lenses. Can you guess what they are? Click on it to see the answer. This diagram click it to see a bigger version shows how a magnifying glass bends light rays to make things look bigger than they are.

Many optical devices use the same basic idea of bending the light to fool your eye and brain so light LOOKS like it came from a different usually larger or closer object. Move the magnifying glass up and down. Lenses are everywhere and have a purpose. See if you can figure out what lens is used to Optics in Astronomy and Space Exploration Optics has a long history when it comes to astronomy and space exploration.

Better ground based telescopes and special optical instruments such as spectrometers enabled people to discover many secrets of the universe, and ground based telescopes and scientific optical instruments continue to be used and improved even today.

But since , optics has also been an important part of the Space Age, starting with ground-based telescopes used to track rockets and satellites. See this website to learn more on how the Hubble works. Cloud Synopsys in the Cloud. Community Community Overview. Analog IP Data Converters. Contact Us.

Difference Between Concave and Convex Lens

Optical lenses are polished glass or plastic substrates that are shaped with one or more curved surfaces that transmit light. Optical lenses may be used either uncoated or with an antireflective coating depending on their intended application. All optical lenses have a focal length which is the distance from the lens to the focal point along the optical axis of the lens. Three factors determine the focal length of a lens; the radius of curvature of the lens, the refractive index of the substrate from which the lens is made, and the medium in which the lens resides.

In this post, we will examine the difference between concave and convex lenses. Also, we will learn about the types of lenses, and different types of images formed by these lenses. When the ray of light enters from one medium to another, it deviates from its original path. This bending of the light ray is called refraction of light.

Concave and Convex are two types of lenses that possess variation in physical shape as well as their properties. The crucial difference between concave and convex lens is that a concave lens diverges the light rays that incident on its surface.

A lens is a transmissive optical device that focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material , while a compound lens consists of several simple lenses elements , usually arranged along a common axis. Lenses are made from materials such as glass or plastic , and are ground and polished or molded to a desired shape. A lens can focus light to form an image , unlike a prism , which refracts light without focusing.

A convex lens plus lens is like two prisms placed base to base. Light passing through a convex lens is converged. Convex lenses are used to treat presbyopia, hypermetropia and aphakia.
