Traceability of photometrical and radiometrical quantities between LNE/INM and DMDM

Project Description

Since the activities in photometry and radiometry at the BIPM were closed down in 2003, the DMDM now consigns the LNE-INM to accomplish the calibration of different photometrical and radiometrical standards to maintain traceability of the units of luminous flux, luminous flux and spectral power responsivity.

At the LNE-INM, the realization of the lumen, the unit of luminous flux, is based on the French candela by employment of a goniophotometer. The candela, the unit of luminous intensity, is based on radiant power measurements transferred by a photometer. Thus, the luminous intensity and flux standard lamps of DMDM will be calibrated on a regular time schedule at the LNE-INM.

Spectral power responsivity of three DMDM silicon detectors (S 1337 BQ silicon photodiodes) will be calibrated regularly by LNE-INM by comparison with trap detector. The agreed monochromatic wavelengths include: 340 nm, 360 nm, 380 nm, 400 nm, 450 nm, 455 nm, 473 nm, 488 nm, 500 nm, 515 nm, 543 nm, 550 nm, 600 nm, 612 nm, 633 nm, 650 nm, 700 nm, 750 nm, 800 nm, 850 nm, 900 nm, 950 nm and 1000 nm.

Progress Report 2018-01-22

DMDM didn't have activities in the past year (2017) regarding EURAMET project no. 1067. Calibration of detectors and luminous intensity standards are planned for current year.


Progress Report 2016-01-24

No activity in 2016.


Progress Report 2016-08-02

It hasn't been activity on project in 2015. We expect that next calibration of group luminous intensity standard and three detectors we will perform in start 2017.
