Why is Inproved TK566 UV Flashlight so Popular?
No matter interested in antique identification, but introducting to the friend recommended this brand.
What is UVC?
UVC (280nm-200nm): short wavelength with the weakest penetrating power.
What is UVB?
UVB (315nm-280nm): Medium wavelength with medium penetration, its shorter wavelength part will be absorbed by transparent glass.
What is UVA?
UVA (400nm-315nm): UVA has the longest wavelength and strongest penetrating ability.
The wavelength of ultraviolet rays
Since the ultraviolet rays radiation with a wavelength less than 200 nanometers will be strongly absorbed by the air, we basically only study ultraviolet rays with wavelengths above 200nm in our applications.
Ultraviolet radiation
The current national standard in China is according to Article 845-01-05 of GB/T2900.65-004 "Electrical Terminology Illumination".
What is the ultraviolet wavelengths?
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 [...]
Ultraviolet energy
We know that the shorter the wavelength of the ultraviolet photon, the greater the ultraviolet energy.
Ultraviolet Rays
The light source emit ultraviolet rays and propagate in the medium. Ultraviolet rays becomes energy transfer afterwards by absorbing of the material.
The ultraviolet rays transmiting way
The third is that when ultraviolet rays transmiting on the way of encountering two different media interfaces. Part of ultraviolet rays is to reflect and the other is to refract.
How to increase the radiation intensity?
The second is the law of independent propagation. When the two beams meet during the propagation process,
The process propagation of ultraviolet rays
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 [...]
