What are optical lenses?

An optical lens is a type of device that uses light to focus an image onto a viewing surface. They are used in surveillance, smart home, industry, automobile, and microscopes.

Understanding how optical lenses work

One of the main functions of an optical lens is to magnify an image by creating a composite of individual images that, when viewed together, create a larger image. The different parts of the image are then magnified according to their distance from the lens. For an object to be seen clearly, the lens must be focused on it. Depending on how far away it is from the lens, you can use a mirror or use a system with lenses. When an object is placed at the focal point of the lens, all light that enters the lens will pass through it and be focused on it. Any objects in the way will block light waves and hence any objects in their way would not be easily seen as if they were blurred or out of focus.

Guide to different types of optical lenses

Optical lenses come in many shapes and sizes, each designed for a specific use. Here’s a closer look at optical lenses:

Convex lenses magnify objects on the screen or in front of the camera, as well as a correct vision by bending light rays into the eye.

Concave lenses reduce glare. They’re perfect for when you’re trying to shoot a video interview or photo with someone close to the camera.

Prismatic lenses have multiple surfaces that curve in different directions creating a wide-angle view. It is often used in cameras and telescopes to create a wider view of their subject.
