High power UV light has become an indispensable tool in various industries, from scientific research to industrial applications. This article will provide an in-depth introduction to the field of high power UV light, covering its principles, applications, and future trends.

Principles of High Power UV Light

High power UV light refers to a type of ultraviolet light with high energy and intense light intensity. It is typically produced by a UV lamp or a laser device. The wavelength of high power UV light ranges from 10 nm to 400 nm, and its energy is much higher than that of visible light. High power UV light can be divided into two categories: UV-A (320-400 nm) and UV-B (280-320 nm). UV-A light has a weaker biological effect, while UV-B light has a stronger biological effect. The generation of high power UV light relies on the excitation of electrons in atoms or molecules. When high-intensity electric current passes through a discharge tube filled with low-pressure mercury vapor, the mercury atoms are excited and emit UV light. The light intensity and energy of the emitted light depend on the power of the electric current and the length of the discharge tube.

Applications of High Power UV Light

High power UV light has a wide range of applications in various fields. The following are some of the most common applications: 1.
