The goal of the LAS&O technology platform is threefold
-
to provide support to unexperienced people who are interested in optical methods for their own research
-
to lend small optical equipments (spectrometer, powermeter, ...) to occasional user
-
to gather large optical equipments
Expertise
Long experience with the realisation of optical devices (interferometers, deflectometer, electro-optic sampling, microscopy, ...).
