Due to the wide range of ultraviolet wavelengths from 10nm to 400nm.It is necessary to perform a more detailed classification.As base on ultraviolet wavelengths's optical characteristics to facilitate industrial applications.At present, the international society and the domestic vertical industries have different classifications.But we have made a more authoritative specification based on the standards of the lighting industry. According to the classification of ISO-DIS-21348, ultraviolet wavelengths are divided into the following 10 categories: Name?Short?Wavelength?EnergyLong wave ultraviolet light, ultraviolet light A, or black lightUVA400–315nm3.10–3.94eV?Short UltravioletNUV400–300nm3.10–4.13eVMedium wave ultraviolet light, ultraviolet light BUVB315–280nm3.94–4.43eVMid-ultravioletMUV300–200nm4.13–6.20eVShortwave ultraviolet light, ultraviolet light C, germicidal ultraviolet radiationUVC280–100nm4.43–12.4eVLong ultravioletFUV200–122nm6.20–10.2eVVacuum UVVUV200–100nm6.20–12.4eVLow-energy ultravioletLUV100–88nm12.4–14.1eVHigh-energy [...]

As you know, ultraviolet light is invisible light. It is essentially an electromagnetic wave And its application characteristics are based on wave-particle duality.Therefore, whether it is the application of ultraviolet light or the development and design of ultraviolet flashlight products.It is all based on the basics of optical characteristics. For the volatility of ultraviolet light, it mainly describes the process of its propagation. It also applies to the three laws of light propagation: The first reason being that ultraviolet rays travel in a straight line in a vacuum or the same homogeneous medium.It reflects the characteristics of the direction of [...]

Ultraviolet light belongs to invisible light, and the essence of light is electromagnetic waves. Electromagnetic waves also have wave-particle duality,that is, energy is analyzed from the perspective of particles (called photons), and its propagation is analyzed from the perspective of waves(it can be simply imagined as each particle propagates in space according to a certain regular trajectory). The shorter the wavelength of the electromagnetic wave, the greater the energy of the photon, the greater its permeability, and the greater its harmfulness.We are familiar with these characteristics as X-rays, which can penetrate the human body and be medically filmed. At the [...]

In 1801, German physicists discovered is a section outside the purple end of the daylight spectrum. It could sensitize photographic films containing silver bromide.And thus discovered the presence of ultraviolet rays. But at that time there was no concept of electromagnetic waves,The scientific community did not reach any agreement on the nature of light. It was not until the wonderful Maxwell equations were summarized. To put forward that people gradually realized the series of invisible rays. Such as ultraviolet rays and others that the eyes can’t see are essentially electromagnetic waves. Now that we know ultraviolet light is an electromagnetic [...]

We want to understand UV flashlights, or UV-related equipment. First of all, we need to understand what is UV and what is its essence?Only in this way can we make better use of related UV products in our lives. In fact, in our daily lives, we may or may not be exposed to ultraviolet rays, but we have not seriously understood what it is. For example, some people are accustomed to referring to ultraviolet light equipment as purple light equipment.We know that the focus of sun protection is to prevent UV sunlight. People also know that a proper amount of [...]
