Domes made of Sapphire, glass, spinel, ZnS, MgF2, flat protection windows for marine and aerospace need high precision during prosessing and quality control.

We have 20 years’ experience developing and manufacturing silicon or Zerodur mirrors and sapphire crucibles for crystal growth in the space. High flatness, surface quality and material purity as well as vacuum-tight connections are required for these applications.

We manufacture different crystalline materials. The procurement of these materials for optical components takes place worldwide and via versatile proven channels so we can ensure independent and reliable supplies. We take care of the choice of the right material as well as its specification, quality check and its traceability.
