Spectral responsivity of UVC detector range This is the bases for accurate UVC measurements with such a UVC meter. This means our UV detectors often offer several calibration entries for different UV sources. Gigahertz Optik GmbH offers a comprehensive range of UVC radiometers, UVC light meters and UVC spectroradiometers designed and calibrated for the accurate measurement of irradiance and dose of all these germicidal UV source technologies. See application note about Germicidal UVC Standards for a full description. Our range of UVC radiometers enable measurements in accordance with important standards for germicidal UVC products including IEC/EN 62471, DIN/TS 67506, and IEC 6. New developments in germicidal UV sources of particular note are UV-C LED arrays (265-280)nm and far UV lamps such as excimer KrCl (222nm). Medium and high pressure mercury sources are also in use as well as pulsed Xenon. In order to maintain Ultraviolet Germicidal Irradiance (UVGI) efficacy while ensuring safety from overexposure to UV radiation, measurements of the germicidal sources and areas of application are performed.ĭue to its high and pre-dominantly monochromatic output at 253.7nm, low pressure mercury has historically been the light source of choice in UV-C germicidal applications. ![]() ![]() The COVID-19 pandemic has sparked a marked increase in demand for germicidal UV sources and the need for accurate measurements with suitable UVC light meters. UVC radiation is lethal to airborn pathogens that can cause diseases like tuberculosis. Short wavelength high energy ultraviolet radiation in the UV-C spectral range from 100 nm to 280 nm is widely used in the germicidal and bactericidal disinfection of air, surfaces and water.
