The wavelength range of near-ultraviolet light is between 200 nanometers and 400 nanometers, and it is a type of ultraviolet light. Near-ultraviolet light is widely used in daily life, for example, in sterilization, ultraviolet lamps, ultraviolet water purifiers, ultraviolet insect-absorbing lamps and other fields. In addition, near-ultraviolet light is also widely used in the field of scientific research, such as spectrophotometers, fluorescence spectrometers and other instruments in the laboratory need to use near-ultraviolet light source.
It is worth noting that near-ultraviolet light is harmful to the human body. Prolonged exposure to near-ultraviolet light can cause damage to the skin, eyes and so on. Therefore, when using near-ultraviolet light, you should pay attention to safety measures, such as wearing goggles and protective clothing. In addition, prolonged exposure to near-ultraviolet light should be avoided as much as possible in daily life to avoid unnecessary harm.
The application of near-ultraviolet light is not only limited to the field of science and life, but also widely used in the field of industry and medicine. In the industrial field, near-ultraviolet light can be used for material surface treatment, printing, coating, photolithography, precision processing and other fields. In the medical field, near-ultraviolet light can be used for the sterilization of medical equipment, treatment of skin diseases, treatment of certain cancers and so on. In addition, near-ultraviolet light can be used in the detection of minerals and gemstones, quality testing of food and pharmaceuticals, and other fields.
Although near-ultraviolet light has many applications, it also has some hazards. Since near-ultraviolet light has a short wavelength and is very penetrating, it can cause harm to the human body if exposed to near-ultraviolet light for too long. Prolonged exposure to near-ultraviolet light can cause damage to the skin, eyes, and so on. Therefore, when using near-ultraviolet light, you should pay attention to safety measures, such as wearing goggles and protective clothing.
In our daily life, we can avoid prolonged exposure to near-ultraviolet light, such as prolonged exposure to sunlight, by wearing long-sleeved clothes, pants and hats to shield ourselves from the sun. In addition, if you need to use near-ultraviolet light instruments or equipment, you should follow the instructions to operate correctly to ensure the safety of use.
