One of the most thrown-around words in laser tech is “beam quality” but what exactly is it, and why should one care? It makes a difference as to how well your laser is performing the particular task at hand, be it cutting steel, engraving glass, or some other scientific experiment. 1.What Is Beam Quality in […]
Whether a physics student, a science enthusiast, or even an engineer who deals with light, one definetely would have heard the word “wavenumber” being mentioned once in his way. But what does that term mean, and why should one take an interest in it? It is time to delve deep into this mystery idea, dig up the importance it carries, and find out why it plays such a vital role in the world of optics, waves, and light. In other words, the wavenumber is the number of wave cycles in any given linear unit of distance. As a matter of fact, much of this […]
If ever reflection and polarization of light puzzled you, you probably have heard something about Brewster’s angle. In fact, such an interesting optical effect has found broad application in quite a few fields of activity, beginning with laser systems and photography, and ending with many others. In the following article, we will explain what Brewster’s […]
Understanding Numerical Aperture (NA) is crucially important in optical systems where precision and clarity matter. The performance and quality of lenses, microscopes, and fiber optics depend hugely on numerical aperture, as it would affect anything from image resolution to light-gathering capabilities within those lenses. This article takes a closer look at what numerical aperture is, […]
Ever wondered why a lake appears so much darker when viewed directly but then changes into a mirror at a shallow angle, or why shiny surfaces happen to be so much brighter at some view positions? These can be explained by applying the very basic notion of Fresnel reflection in optics that helps explain how […]
The Greek alphabet is conventionally used in photonics to represent multiple physical quantities, variables and constants. Greek letters represent an internationally comprehended language in which many important physical quantities and variables are represented. It provides clarity and consistency in communicating research papers, technical documents, and lectures all over the world. In the time of Greek […]
Have you ever held a smartphone, browsed the internet, or video-called your friend from the other part of the world? All these everyday activities depend on a magical science called photonics, actually lying at almost every modern technology backbone. But what, precisely, is photonics, and why should it matter? What Does Photonics Mean? Photonics is […]
Just think about a sunny day outside, where the heat of the sun touches your skin. Actually, you are being bombarded by billions of tiny particles called photons streaming from the Sun across 93 million miles of space to reach Earth. Moving with such energy, these particles light up all that they touch, heating your […]
Within optical fiber technology, the Mode Field Diameter (MF) is the term used to define the effective width size of the light-carrying core in single-mode fiber. While in multimode fibers multiple light paths are being guided, in single-mode fibers, only one mode of light is transmitted. MFD is very important in order to understand how […]
The article presents the value of the V parameter, its origin, and its main applications in a manner that is easy to comprehend for the understaning of this important feature of fiber optics.
