Unlike visible light, which ranges between 380 nm and 780 nm, ultraviolet (UV) light wavelengths measure between 100 nm to 400 nm. UV is broken into subcategories known as UVA, UVB, or UVC. While UVC rays are the shortest and strongest, naturally occurring UVC rays are mostly absorbed by the atmospheric ozone layer, so they […]
Ultraviolet (UV) light, illuminance, temperature and humidity are all very harmful factors in a museum or an archival institution. These factors can all negatively affect the quality and longevity of a piece of art or artifact if the piece is exposed to extremes for too long. Data loggers that measure/monitor critical parameters and communicate with […]
