Device for the production of organic films of different compositions by plasma induced by microwave discharge

The system is associated with a mixing line and a pumping system. This makes it possible to control the composition of the initial gas mixture sent into the reactor and maintained at low pressure. The plasma that forms in the reactor is induced and maintained by a microwave discharge coupled with an Evenson cavity. The device is such that part of the solid organic matter produced is deposited in the form of a thin film directly on an ad hoc support, facilitating subsequent characterizations, particularly by infrared.

REMi

REMi (Reflectance d'Échantillons Microscopiques), spectroscopy device for microscopic samples in the visible and near infrared in a clean room.

Contacts : Zahia Djouadi, Cateline Lantz, Rosario Brunetto

The sample under the microscope is illuminated (via a fiber) by a halogen lamp, it reflects part of the light which is collected by a second fiber and routed to a spectrometer with a spectral range [0.45, 1.0] µm.
