Photometry and Radiometry Standards Research

MSL's research into light standards consists of three main projects: Photometry, Radiometry, and Solar Energy.


You can find out more about our research in Photometry here >>


  • Light and colour measurement
  • Calibration of spectral responsivity of silicon diodes and silicon diode trap detectors referenced to a cryogenic radiometer using stablised lasers
  • Development of improved trap detectors
  • Ultraviolet measurements and instrumentation including solar ultraviolet for ozone, health and environmental purposes.
