Viso’s goniometers can also be used to measure UV desinfection lamps, which are increasingly popular these times. Normal spectrogonio sensors operate with wavelengths from 360 to 830nm, but choosing a sensor that goes down to 190 nm enables a standard goniometer to measure both UV-A, UV-B and UV-C. The sensor is somewhat more expensive but please contact us if you are interested in such a solution.
