Optical radiation is part of the electromagnetic spectrum. It is subdivided into ultraviolet radiation (UV), the spectrum of light visible for man (VIS) and infrared radiation (IR). It ranges between wavelengths of 100 nm to 1 mm. Electromagnetic waves in this range obey the laws of optics – they can be focused … See more Optical radiation may be produced by artificial sources, such as UV lights, common light bulbs, and radiant heaters, but the primary source of exposure for most people is the sun. This exposure can result in negative … See more The European Union (EU) has laid down minimum harmonized requirements for the protection of workers against the risks arising from exposure to Artificial Optical Radiation (e.g. UVA, … See more
