What is a UV intensity meter?

An ultraviolet intensity meter is a device that measures the intensity of ultraviolet rays. Ultraviolet light has a very short wavelength and is invisible to the human eye. Generally, light from 10 nm to 400 nm is in the range of ultraviolet rays. Ultraviolet rays have a short wavelength, so they have high energy and a high bactericidal effect, so they are used for sterilization, and they act with oxygen to produce ozone. On the other hand, DNA has an absorption band at a specific wavelength of ultraviolet rays, and when DNA absorbs ultraviolet rays, the DNA is damaged, which is harmful to the human body. Since it has various other functions, it is a very important light source in the industry. For this reason, it is important to measure UV light, and a UV intensity meter is required to measure the intensity.

Application of UV intensity meter

Ultraviolet rays have a wide range of uses. The action of curing the resin is that it is hardened by irradiating it with ultraviolet rays when packing the resin at the dental clinic. Ultraviolet light is also used to cure semiconductor resists. At this time, if the intensity of the ultraviolet rays decreases due to deterioration of the lamp for ultraviolet irradiation, it will not harden well, so it is necessary to check the intensity regularly with an ultraviolet intensity meter. In addition, when conducting experiments using ultraviolet rays in the laboratory, when evaluating the characteristics of solar cells, in the medical field such as treatment of white spot disease, and when using ultraviolet rays for sterilization of food etc. Ultraviolet intensity meters are used for the management of.
