Mission
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,听 deflectometer, electro-optic sampling, microscopy, etc).
