Company Description

ZMKJ is a worldwide supplier of single crystal Germanium lens and
single crystal Ge ingot , we have a strong advantage in providing
single crystal wafer to micro-electronics and opto-electronics
industry in diameter range from 2 inch to 6inch .
Ge wafer is an elemental and popular semiconductor material , due
to its excellent crystallographic properties and unique electric
properties , Ge wafer is widly used in Sensor , Solar cell and
Infrared optics applications .
We can provide low dislocation and epi ready Ge wafers to meet your
unique requirement. Ge wafer is produced as per semiconductor,with
a good quality control system , ZMKJ Is dedicated to providing
clean and high quality Ge wafer products .
we can offers both electronics grade and IR grade Ge wafer , please
contact us for more Ge product information.

In the range of 2-12 μm, germanium is the most commonly used
material for the production of spherical lenses and windows for
high efficiency infrared in imaging system. Germanium has a high
refractive index (about 4.0 through 2-14μm band), usually do not
need to be modified due to its low chromatic aberration in low
power imaging systems.
Single Crystal Germanium Wafer Capabilitywe can offer both electronics grade and IR grade Ge wafer and Ge
ingot , please contact us for more Ge product information .
