The improved utilization of natural resources, the detection of undiscovered reservoirs and the examination of climate changes – these are only some of the challenges which are met using geostationary satellites. Science today owes a great deal to these “artificial” eyes in space. That’s why the optical system integrated in the satellite plays such an important role – it is crucial for the success of a mission. Materion Balzers Optics has made a name for itself as manufacturer of optical filters for space applications. Whether it’s about bandpass filters in the VIS, NIR or SWIR range, sometimes with a range of mere nanometers – our experience in production and qualification provide the foundation for a great number of successful projects.
