Optical Solar Reflectors

RUAG Space offers the procurement and installation of small highly reflective mirrors called Optical Solar Reflectors (OSR) to structures.

An innovative process allows the bonding of mirrors with electrical conductive front surfaces to Aluminum structures or panels achieving electrical connection between OSR and Aluminium.

The result is a highly effective thermal radiator at a mass around 1kg less per m² than traditional bonding processes.


  • Electrical conductive or non-conductive front OSR surface
  • Qualified between -70 and + 70°C structure temperature
  • Large areas up to ~2.5 x ~2.2 m can be covered in one manufacturing process
  • High percentage of covered area
  • Custom cut OSR shapes possible
