1040213403 Application Field and Working Principle

Optical lenses are a widely applicable and fundamental optics component used in many different fields. By understanding its application field and working principle, we could gain an insight into their use in such fields.

Application Field

Optical Lenses can be found in many industries, such as telescopes, cameras, microscopes, eyewear, displays, industrial imaging measurement and medical equipment.

Telescopes and optical microscopes make use of both objective and eyepiece lenses so that one can observe far away objects in the night sky, and observe extremely tiny objects such as cells under a microscope. Eyewear use lenses to correct vision problems, as well as serve the protective purpose of sunglasses. Displays, such as those found on TVs and phones, refract light to create the images seen. Industrial imaging measurement techniques such as laser triangulation, structured light, and barcode readers, make use of lenses to capture the necessary data. Lastly, medical equipment such as endoscopes, laparoscopes, and photography equipment all employ optical lenses as well.

Working Principle

Optical lenses are simple to understand but difficult to manufacture. Light is a kind of wave, and the wave characteristics will change due to lenses. Optical lenses are classified according to refractive index and focal length. The refractive index is the amount of light refracted by a lens. The focal length is the distance between the front vertex of a lens to the point where the light converges after being refracted by the lens.

Optical Lenses, depending on their focus and refractive characteristics, can provide advantages like image enlargement, image condensation, image improvement (correction of aberration) and so on. By changing the characteristics of these lenses, we can control the quality of the light being refracted and the image being produced. It is these characteristics that make optical lenses an invaluable component in many industries.

Conclusion

In conclusion, optical lenses are an incredibly versatile and useful component found in many different industries, such as in telescopes, cameras, eyewear, displays, and industrial measurement. By understanding its application field and working principle, we can gain insight into the various uses it has in different industries.
