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.
