Measuring, determining and processingGermanium (Ge)

Germanium is a particularly versatile material used primarily as a mono- or polycrystalline raw material for sophisticated applications in optics and optoelectronics, metrology and many areas of research and development. The very brittle material is often used to manufacture special structural components or customised products as one-off items or for very small series. Germanium has very good transmission properties in the infrared range, and is accordingly well suited for many applications in the field of optics and optoelectronics.

The processing possibilities of germanium, a material with very good machinability, are manifold: The high-purity, crystalline material can be sawn, ground, milled and drilled, although a great deal of care and experience is required in machining due to its extreme brittleness and the high raw-material price of the sensitive material. We can guarantee both precise and efficient handling of the workpieces.
