Always on the leading edge of optomechanical development Optec is directly involved in design and engineering of optical systems for satellites. All materials involved in space applications are the state of the art for space applications. Extremely low out gassing materials, special and exotic alloys, and technical development expertise all merge together to design the most advanced space compliant optical systems. All environmental and mission conditions are analyzed carefully with proper FEA software and real test and experiments to certify compliancy to customers specifications. Optec is involved in the design and manufacturing of many On Ground Support Equipments used to verify functionality and calibration of optical systems to be used in space, like as an example the new Sentinel 4 produced for ESA. Two clean rooms in class ISO5 are available in Optec in order to guarantee level of dust and particles contamination for Space applications in all
