Manufacturing High-Quality Germanium for Infrared Optics

Germanium’s properties make it the material of choice for both mid-wave (MWIR) and long-wave (LWIR) infrared systems, essential for aerospace, defense, and medical technology applications. Infrared optical systems are often required to operate in multiple wavebands, highlighting the criticality of the material to the optics industry. Equally critical is control of the growth process to ensure high quality and optimal performance.

This presentation covers the fundamentals of the Czochralski (CZ) growth process for producing high-quality germanium crystals. Additional topics will include the challenges associated with the optical industry’s drive to larger components, high transmission, and tight windows for electrical resistivity.

Gill highlights the transformation of raw Germanium into precision optical components that power today’s most advanced infrared systems.
