The lens definition
The optical lens is usually made of common materials such as glass, BK7, quartz, and sapphire.
Their function is to change the direction of the light through refraction or reflection. Therefore, they can achieve image focusing, magnification, or correcting optical aberrations, etc.
You may not have seen it, but it is an essential component for some optical instruments in real life.
It provides convenient services for your life. At the same time, it can also meet some scientific research needs. This article will explain the optical lens to help you understand its working principle and applications.
The working principle of optical lens
The basic function of an optical lens glass is to converge or diverge light through refraction or reflection, thereby changing the direction of light propagation and achieving imaging, focusing, or beam control.
- Refraction
When light passes from one medium into another medium, due to the difference in their refractive indices, the light product classificationwill be deflected.
Optical lenses take advantage of this property to work.
- Imaging process
Converging lens (convex lens): It can focus parallel rays of light onto a single point, forming a real image.
Diverging lens (concave lens): It can cause parallel rays of light to diverge, making it seem as if they are coming from a virtual focus.
Optical lens classification
The shape of a lens refers to the physical curvature of its surface. The shape and material of the lens significantly affect the way it refracts light.
Lenses can be convex, concave, or a combination of both, and each type bends light in a different way.
Convex lenses converge light and focus it, while concave lenses disperse light, causing it to spread out.
Different forms of lenses have different functions. Therefore, people often choose different lenses based on their purposes.
The optical lens can be classified according to their functions:
- Convex Lens
Converges light to form a real image
- Concave Lens
Scatter light and form an image
One side is flat, the other is convex, allowing light to be focused.
- Plano-Concave Lens
One side is flat, the other side is concave. People often use it for spreading the light beam.
- Double-Convex / Double-Concave Lens
Double convex: Light convergence
Biconvex: Light divergence
What are the uses of optical lenses?
The uses of lenses are extremely extensive.
Whether in the field of medicine, in the field of astronomy, or in other environments, you can always see the presence of lenses.
You will use lenses in many devices. The following situations are some common usage scenarios. You can choose different lenses according to the purpose.
