Introduction Measurement and analysis of light sources and lighting fixtures is impossible without the use of goniophotometry and photometry. Light may be measured in two distinct ways, but both methods have different characteristics, approaches, and uses. The purpose of this article is to clarify the differences between goniophotometry and photometry by discussing their underlying concepts, key m...
Introduction Evaluation of color quality is essential in many different industries, including lighting, automobiles, textiles, and cosmetics, to name just a few of them. The accurate measurement and evaluation of a color’s qualities are necessities if manufacturers are to ensure that their products always have the color look they seek. In recent years, there has been a shift toward the use o...
Ozone testing is a common method for testing the weather resistance of materials, mainly used to evaluate the durability performance of materials in ozone environments. Ozone is a highly reactive oxygen molecule that can react with double bases in materials, leading to material aging and deterioration. Therefore, ozone resistance is very important for many experiments. In ozone testing, the teste...
