Germanium (Ge) is a high-refractive-index material well-suited for manufacturing infrared optical (EO/IR) lenses, windows, and mirrors.
We specialize in the custom growth of Czochralski (Cz) crystals in hard-to-find sizes or unique orientations, with custom electrical resistivity and special optical transmissions.
There are several technical challenges in manufacturing germanium components for infrared optical systems, such as maintaining high optical quality over a wide range of temperatures, minimizing unwanted radial resistivity gradients, and reducing the absorption of infrared radiation.
Rely on our talented crystal growth technicians to overcome these challenges and deliver demanding specifications.
Optical precision is critical to meet specific requirements related to accuracy, surface quality, and overall optical performance.
Our ISO 9001:2015 Quality Management certification enables us to ensure your infrared optical lens meets or exceeds your expectations.
We fabricate germanium components, including optical lenses, prisms, and optical filters, with extremely high precision, ensuring exceptional performance in a wide range of infrared optical applications.
