Optical Assembly

In the Optical Assembly the incident radiance and irradiance are collected and split according to wavelength and focussed on the detector modules of the two optical channels. The Optical Bench consists of a single aluminium structure in which all elements are mounted. Attached to this aluminium structure are the two Detector Modules. The Optical Assembly Thermal Hardware consists of a thermal radiator and heaters. The thermal radiator is thermally connected to the detector modules via cold-fingers and flex-links. The heaters are attached to the Optical Bench structure and the CCD detectors.

Detector Modules

The main function of the (DEM) is to convert the optical signal provided by OPB, to an analogue electrical signal. The OMI-EOS system includes two identical DEMs. Each DEM consists of a CCD, control electronics and thermal hardware.
