II-VI Optical Systems produces polycrystalline germanium optical blanks up to 18 inches in diameter.

Germanium material grown by II-VI Optical Systems features:

  • Tightly controlled resistivity with overall values ranging from 3-40 ohms-cm.
  • Custom grown and near-net shapes for domes and irregular windows to minimize material fabrication costs.

II-VI Optical Systems' engineers are experienced with a wide range of optical materials for infrared and visible applications. We can provide assistance in the selection of the material best suited to meet your requirements. Contact us to support your product needs.

II-VI Optical Systems has an internal process for recycling germanium scrap. Ge Recycling II-VI Optical Systems grows germanium crystals to support the IR products we produce. We have the radioactive certifications to handle throiated coatings at our site. II-VI Optical Systems is experienced in this area as we deposit thoriated and non-throriated coatings into IR windows. We are compliant with the proper disposal methods to maintain our certificates and are experienced in our recycling process. We maintain our ISO 9001-2000 + AS9100B certifications which are necessary for consistent and repeatable procedures
