Areas of expertise
• Photometry and radiometry and related quantities, such as optical power, radiance, irradiance, illuminance
• Cryogenic radiometry and optical power measurements
• Photobiological safety of light sources
• Calibration of detectors for photometric and radiometric measurements, laser power detectors
• Spectrometer characterisation
• PhD, Astronomy and Astrophysics, 2003
François joined MSL in September 2008, and since then has worked on the realisation of the primary spectral radiometric scale of MSL and its transfer to silicon-photodiode-based detectors, which in turn can be used as working references for calibration of devices for optical power measurement. He is also involved in the calibration of photometric detectors and UV-broadband detectors. Since 2015, he has been responsible for the MSL cryogenic radiometer, which is the primary standard for the measurement of optical power. He is also interested in developing MSL capabilities to test lamps and luminaires for photobiological safety.
He has been a technical expert for IANZ accredited laboratories in the domain of photometric measurements in New Zealand. Before joining MSL, he worked in the area of experimental molecular spectroscopy applied to the exobiology of planetary atmospheres in the solar system and the chemistry of extra-solar planets.
