Introducing the Purple Excitation Lamp: A Game-Changer in the Field of Luminescence and Spectroscopy

Introduction to Purple Excitation Lamp

The purple excitation lamp, also known as the violet excitation lamp, is a specialized light source that emits light at a wavelength of around 405 nm. This lamp has gained significant attention in the field of luminescence and spectroscopy due to its unique properties and wide range of applications. The purple excitation lamp is designed to excite certain molecules, enabling the study of their optical properties and interactions with other substances. In this article, we will delve into the details of the purple excitation lamp, its working principles, applications, and its impact on various industries.

Working Principles of Purple Excitation Lamp

The purple excitation lamp operates based on the principle of fluorescence and phosphorescence. When a molecule is exposed to light at a specific wavelength, it absorbs the energy and becomes excited. The excited molecule then releases the excess energy as light, which can be observed as fluorescence or phosphorescence. The purple excitation lamp emits light at a wavelength of 405 nm, which is ideal for exciting certain molecules and enhancing their luminescence properties. The lamp typically consists of a mercury-vapor discharge tube, which emits ultraviolet light when an electric current passes through it. The ultraviolet light then passes through a filter that selectively transmits light at 405 nm, resulting in the purple excitation light. This light is then directed towards the sample, exciting the molecules of interest and enabling the observation of their luminescence properties.
