UVS, Broadband UV Radiometer
UVS instruments are fully weather protected and suitable for use in all environments. A precision quartz dome and specially shaped diffuser provide class-leading directional response. The detection system includes optical filters and a phosphor that determine the spectral response. The phosphor is very sensitive to low levels of ultraviolet radiation and is stimulated by the UV to emit green light, which is detected by a photodiode. The system is temperature stabilised at +25 °C to prevent changes in spectral response and sensitivity with variations in the ambient conditions.
