Understanding K Correlation in Optical Design: Managing Stray Light and Light Scattering
In this article, we will explore a critical aspect of optical design: the K correlation, and how it plays a pivotal role in managing issues such as stray light and light scattering in optical systems, and we will discuss the Bidirectional Scattering Distribution Function (BSDF) in greater detail. The Significance of K Correlation In optical […]
5 things to know about refractive index
Introduction The refractive index is one of the basic concepts in optical sciences. Same as volume, and density, the refractive index is a fundamental property of all materials. However, not only materials that are used in optics have a refractive index. For example, the refractive index of water is 1.33, and the refractive index of […]
Why spot and beam uniformity are not always equal
For many LED optic projects, a spot size and beam angle can be specified with a single uniformity value. In cases of beam angles above 30 degrees, things get tricky. Please see the images below for an explanation. If you prefer to understand the math… Illuminance is changed by formula E=(I/r*r)*cos(A), where E – illuminance, […]
Uses of Sapphire explained; IR optics, laser optics, windows
Introduction You may not be aware but you probably have in your hands one of the toughest substances in the world right now. If you own a good quality watch chances are that it has a sapphire glass. Also, some versions of Appla watches and almost all mobile phones use sapphire lenses on their cameras. […]
