The Mesolens can currently be used in two modes:

as a camera lens
- for widefield epi-fluorescence and brightfield imaging. Short exposure times (<s) are typically used (even for very weakly emitting specimens) due to the high efficiency light pick-up.
in confocal mode
- in this mode the large scanning galvo mirrors are operated with a maximum frequency of 100Hz (120 seconds per Nyquist sampled image consisting of 20,000 x 20,000 pixels). Both modes provide data-rich images: up to 500 Mbytes per detection channel.
