OGSE CFO (Collimation and Focalisation Optics)

The CFO are parts of the MTG program. It will be used to characterize for the integration and characterization of the MTG element an interferometer assembly.
The Collimation Optics creates a collimated beam with the same pupil and field of view as the tested element.
It collects the light of the element output to image it on an infrared camera.

The CFO is composed of silicon lenses which were machined at AMOS.
The development of the CFO implies:

Optical design and analysis
Opto-mechanical analysis
Manufacture, integration and tests
Test with laser class 2B
