Uncertainty in UV-C Sensor Calibration
By Dan Scharpf, Ph.D., Chief Technologist, Labsphere, Inc. Ultraviolet Germicidal Irradiation (UVGI) is a proven method of disinfection for both bacterial and viral pathogens. To ensure germicidal efficacy is achieved, UV-C light sources need accurate characterization of irradiance (optical power over a given area) and dose (irradiance x time). Knowing the limitations of the … [Read more...] about Uncertainty in UV-C Sensor Calibration
