Crystal Growing

Hellma Materials IV IR Optics has developed world class expertise in growing large germanium crystals. Mono crystals with diameter of 350 mm are routinely grown
in our Czochralski type crystal pullers.

For special applications Hellma Materials IV IR Optics can provide germanium crystals with diameter of >450 mm.

In our crystal lab we are able to analyze and characterize crystal structures so we can guarantee exact crystal orientations and material specifications.

Hellma Materials IV IR Optics can respond to any request that our customers require in terms of material and crystal characteristics.
