265 nm UV light, a part of the ultraviolet (UV) spectrum, has gained significant attention in various industries due to its unique properties and applications. This article aims to provide an in-depth introduction to the field of 265 nm UV light, covering its characteristics, uses, and the industries that benefit from its applications.

Characteristics of 265 nm UV Light

265 nm UV light falls within the vacuum UV (VUV) region of the electromagnetic spectrum. It is characterized by its high energy and short wavelength, which allows it to penetrate materials more effectively than longer wavelengths of UV light. This makes it highly effective for various applications, such as sterilization, water purification, and material processing. One of the key features of 265 nm UV light is its ability to produce highly energetic photons that can break down molecules and destroy harmful substances. This property makes it an ideal choice for applications requiring deep penetration and effective disinfection. Additionally, 265 nm UV light is less absorbed by oxygen and nitrogen compared to longer wavelengths, which means it can be used more efficiently in air and gas treatment processes.
