SpaceTech develops laser optical instruments for earth observation missions, specifically instruments requirering highly stable laser sources e.g. for heterodyne interferometers and trace-gas measurements. For this, SpaceTech has built up a team of laser specialists covering the required areas of competency optical, optomechanical to optoelectronical design.

Full instrument development cycle
  • Instrument concept design
  • Detailed optical, mechanical and electrical design
  • Manufacturing and test of carbon fibre-glas and metal-glas optomechanical components, including qualification of flight hardware.

SpaceTech maintains an active network to institutes and companies in the field of laser optics providing access to state of the art knowledge and technology.
