WG 1 – Objectives
Comparison of fluorescence intensities between images requires measurements of the illumination power and stability of the excitation light source. WG1 aims at establishing a recommended protocol for measuring the stability of a light source during both short- and long-term image acquisition sessions using calibrated external power sensors. This initial aim will be extended later to measure the absolute flux of light through the illumination path and irradiance of the sample. The initial protocol will be designed around lasers on confocal microscopy platforms (raster scanning and spinning disks). It will be later modified towards other microscopy techniques (widefield, TIRF, light-sheet, super-resolution).

WG 1 - Latest News
Last meeting: 1st October 2025, 5:00 pm
Release of protocol “Illumination power and illumination stability measurements for contocal, widefield and multiphoton microscopes“.
Beside step-by-step instructions, the protocol provides:
- A link to a public database with measurements made by members of our group and to which you can contribute by uploading your own measurements.
- A link to a GitHub repository with scripts to automatize the measurements with some scopes and power meters
- A link to tutorial videos which are available on the QUAREP-LiMi YouTube Channel
- Automation
- Aims: The QUAREP-LiMi power and stability assessment protocol requires long and repetitive measurements for each light source as other parameters are tested. The aim of this subgroup is to provide feasible means for carrying out these processes, taking advantage of the automation capabilities of modern microscopes.
- Co-leads: Mišo Mitkovski, Nasser Darwish
- On-going tasks:
- Published scripts and instructions for Nikon and Zeiss microscopes in the QUAREP-LiMi Github repository.
